Chem 120 Syllabus

Course Description and Direction

Chemistry 120 is the continuation of an entry-level course in quantitative chemistry intended for majors in chemistry and biochemistry.  The course provides a background in basic equilibrium calculations, data analysis, and laboratory practice in classical chemical titrimetric analysis and elementary instrumental analysis using electrochemical, spectroscopic and chromatographic measurements. The student in Chem 120 is presumed to taken Chem 119 or to have otherwise gained a background in basic chemical stoichiometry, equilibrium theory and acid base reactions, error propagation, and simple statistics.

Topics introduced in Chem 120 include the quantitative treatments of chemical equilibrium in formation of complexes, in redox reactions, and in solvent extraction, and the theory and practice of chromatographic separations with brief introductions to modern chemical analysis based on electrochemical theory and measurements and to quantitative measurements of the absorption of light by chemical systems.

Course Objectives:

This course focuses on the development of quantitative measurement and computational skills relevant to the chemical and biochemical sciences and on the strengthening of laboratory and theoretical skills developed in Chem 119.

At the completion of this course, students will be able to:
1. Perform and evaluate basic titrimetric analyses using metal complexing agents, acid/bases, and redox reactions
2. Perform and evaluate basic quantitative measurements of amount based on measurement of electrochemical cell potential and current.
3. Perform and evaluate quantitative measurements of concentration via absorption of light by chemical mixtures.
4. Perform and evaluate quantitative separations of simple mixtures using chromatography.

Required Texts:    

1. G.D. Christian, Analytical Chemistry, 6th Ed., 2004. ISBN-0-471-21472-8. This was the text used in Chem 119 last Fall.
Note that you will need access to a computer with a working version of Microsoft Excel to do homework and labortory work for this course.

Many authors, including Christian, use Microsoft Excel in the solutions to problems and as a general approach to problem solving.
If you want a workable (and FREE!) substitute for Excel – you can find “MS Office-like” software available for download here. (It is a big download, though!)
Just be warned that you need to save your work as Excel-compatible xls files for the staff to access.

2. An InterWrite PRS RF Clicker by GTCO Calcomp for responding to required questions posed during lecture.

The clicker is handled as a textbook at the UD bookstore. This clicker will work in all other courses offered at UD that use clickers so you will need purchase only one clicker during your stay at UD. Note that other manufacturers’ clickers will not work as substitutes. Here is the “fact sheet” that the Bookstore provides with the clicker.

Note: Your clicker needs to be set up prior to the lecture in Chem 120, so that you receive proper credit for your answers in lecture. The clicker has a unique serial number which will be associated to your UDID in the clicker database upon first activation, so you cannot share clickers. If you have not already done this, you will need to set up your clicker with your 5- or 9-digit UDID before you attend the first class of Chem 120. The UD has a website dedicated to student set-up and use of clickers at http://www.udel.edu/topics/clickers/students/. It is your responsibility to ensure that the clicker is properly set up.

Other Required Items:

1. A bound 8” x 10” or 9” x 11” laboratory notebook with sewn-in, numbered pages.  Please note that loose-leaf and spiral notebooks are not acceptible for use in Chem 120. If you have to purchase a new one, get a notebook with about 50 pages or more. Suitable notebooks are available at the UD bookstore. This notebook can be the one you used in Chem 119, and if you have enough room, it also will be adequate for use in Chem 438, a course which also requires bound notebooks.

2.  One pair of chemistry laboratory safety goggles. These must be worn at all times in the laboratory. Suitable goggles can be purchased at the UD bookstore. Biology-style safety glasses won’t be acceptable in Chemistry labs because they lack side protection. Your Chem 119 goggles are suitable for this course and will be suitable for all future Chemistry lab courses at UD, and will probably even work for the Biology labs.

FAQs:           Here you can find answers to many of life’s persistent questions – or at least those from Chem 120.

Lab Notebook Issues

Do I need numbered pages in my lab notebook? Mine has bound pages, but no numbers.

Yes, but you can add the numbers by hand. Just don’t remove any pages, ever – that’s not Good Laboratory Practice (GLP).

Can I white-out/erase mistakes in my lab notebook?

NO! All mistakes should be “deleted” with a single line drawn through them, so that they can still be read.

Can I recopy my notebook? It is so messy!

NO!! Never re-copy! The notebook is a record of your work – so it may not be neat, but any recopying alters that record. Recopying is also not GLP.

How should I organize the notebook?

I like to do all of my calculations on the left side (the back of the previous page) and to record all data and all notes from an experiment on the right side. Then I can check my work if I find an error later. I usually set up the right side to record data and leave the left side blank to allow me to calculate.

What do I do with printouts or other data or calculations not recorded by hand?

I suggest making a copy of the printout and fixing it into the notebook permanently with tape or staples, so it can’t fall out. If the page contains data they go in the areas reserved for data, if it has calculations, they go with the other calculations.

Is it ok to write data on a piece of paper – like the experiment’s results sheet – then record it in the notebook later, so that the data table is neat?

NO! The data always should be recorded directly into the notebook. Never record onto separate paper! And don’t do calculations on separate paper, as you will often not be able to find that paper when you need to check your calculations.

Lab and Exam Makeups and Other Issues

Can I attend another lab if I miss lab? I sometimes can’t make it to lab during my scheduled lab.

If you have a good reason for missing the lab, you need to contact Prof. Brown and discuss it. We may be able to accomodate you. However, you may not attend another lab without the instructor’s permission.

Can I make up or repeat a lab during my scheduled lab? There seems to be time.

Possibly. Many labs have some time built in to permit repeated analyses, and there may be time to work though a mistake made earlier. However, you cannot work past the end of scheduled lab time. Also, a missed lab needs to be discussed with the instructor to allow you to submit results by a different due date.

I broke my buret/pipet and now I need to recalibrate it. Can I attend another lab to do that?

Generally, no. You should be able to do the recalibration in your lab.

I overslept/forgot/was busy during the midterm. When can I take the makeup?

You probably forgot about what it says in the Chem 120 syllabus. Without an excused absence, there are no makeups. With an excused absence, a makeup will be arranged.


Other Requests and Questions

When are the midterms/lab sections/TA office Hours/your Office Hours?

All this and more may be found in the Chem 120 syllabus on line at WebCT and also on the public site. The public site is http://www.udel.edu/chemo/teaching/CHEM120/CHEM120.htm

How do you assign grades in this class?

That is also given in a part of the syllabus. You’ll find ranges and the full disclosure of graded material there.

Why are the exams so difficult?

Because it is such a departure from high-school chemistry course material, Chem 119 and 120 have always been challenging to first year students, especially to those with borderline math skills and study habits. Exams focus on homework and concepts from the book and lecture rather closely, but some of these concepts are not easy for students entering the field after a two-year hiatus from chemistry and algebra. Students who put time into the class – and I suggest 9 focused hours per week of study and work outside of class – generally do rather well in this class. I try to make exams somewhat consistent over the years – though not the same – so that the grades in the course can be compared over the years. There is a metric called discrimination in the theory of evaluation[1-3]. That metric indicates an exam that best discriminates between good and weak students should have a mean near 60%, so the goal is an exam that is not too easy but also not impossible for the average Chem or Biochem student taking this class. Note that this does not imply that exams should provide the same experience for all students: students with superior preparation and good math skills will find them very straightforward, while those with little or no real preparation and a weak background will find them very difficult. I am aiming to get an average near 60%, which is a C in the course scoring system. That score plus real effort in the laboratory (where a 70-75% – a B score – is usually the norm) gives a C+ or B- as the average grade in the course.

[1] W.E. Harris, Analyt. Chem. 1975, 47, 1046A.

[2] R.L. Ebel Essentials of Educational Measurement, 2nd Ed., Prentice-Hall, Englewood Cliffs, 1972.

[3] T.L. Kelley, J. Educ. Psychol. 1939, 30, 17.

Do you “curve” the course? What if we all do terribly? What if we all do well?

I don’t “curve” classes, but I do recognize that grades are not absolute. Using a curve implies that I am convinced that I always have a truly representative sample from the population of all Chem 120 students out there and that every class does the pretty much the same on exams and overall. Experience has shown that I can’t assume that classes behave this way – in fact, my experience is that the student scores have decreased a bit over time. I do have a preset grading scheme which suggests that I can somehow set exams and other tasks that evaluate learning well enough to know that better students will achieve a certain score and weaker students will achieve a lower score. From experience in covering these subjects and in asking certain questions that I know from taxonomy are “easy” and some that are “middle” or “hard,” I can test a wide range of skills and learning. Of course, there is always some uncertainty in any measurement, even in grading. To be fair to students that end up near the boundaries of grades, I always “grade up” on exams and “grade up” on decisions to be made concerning grades at the end of the course, so that any uncertainty in the grading occurs in favor of the student. Then, when I assign grades, I can be sure that a person who misses a cutoff is not being unfairly graded. That is generally why you won’t usually get me to revise a grade by appeal.

So, if everyone in a class somehow could do all the easy stuff and a lot of the harder stuff, it tells me that the average grade should be near “A”. I would award grades accordingly. On the other hand, if everybody in the class couldn’t do easy problems and if I didn’t see any error in instruction, I could not justify the usual grades here, either, and I would grade accordingly. A curve would see these situations as the same, and would adjust things to generate the same average; experience would say that they are not the same, and would demand that the grades be very different. As the course number goes up, the chance that the most of the students perform well also tends to go up, and so do my grades.

I tried to turn in my homework but the mailroom door was locked. Will you accept it?

The mailroom door in Brown Laboratory gets locked at about 4:30PM, but the homework is due earlier, at 12:00PM. I usually post the homework solutions on-line before lecture, so at 4:30 PM your homework would be past the announced deadline for submission. We generally won’t accept late homework.

I can’t make your office hours. Can I come to your office to ask questions at another time?

Yes, but because Chem 120 is only a part of my duties, it is possible that I may not have time when you want to see me, especially if you drop in. If you make an appointment, I will keep that appointment, however.

I am having trouble in Chem 120. Is there extra work that I can do to raise my grade?

While I am sympathetic to students who want to do better, my committment to fairness is paramount: everyone in the course gets the same work and the same chance to show me that they can do that work. There is no chance for individual extra work/credit in Chem 120. I will try to help you improve your scores if I can.

I am having trouble in Chem 120. Can you suggest a tutor who can help me?

Mrs. Staib in Room 102 Brown Lab can help you here. She has a list of tutors, courses that they will tutor and their rates. She will provide that list. If you bring me the list, I may be able to give you my opinion on some of the tutors.

 

Grading:

The course will be marked on the results of clicker questions, exams, homework, laboratory results, and the appearance of your laboratory notebook. The grade given will be determined on the basis of the total number of points earned. The average grade in this course has usually been C+.

 

Here’s how Chem 120 is scored and graded:
Scoring in Chem 120

This is a course that combines lecture and laboratory, and the scoring reflects your performance on homework sets, exams and in the laboratory. Lecture and laboratory performance receive equal weight in setting your grade for Chem 120. 

Laboratory Reports: 225 points

Scoring of labs is based on pre-determined criteria for accuracy and precision expected for a given experiment.
The difference between the reported result and the accepted value for the unknown determines at least 50% of the score for each experiment.  Experiments are also scored on the reported precision when possible, and the reported results here determine 25% of the score for those experiments.  In three experiments (#4,6,7) graph quality also affects the score.

Proper calculation of results is important. Miscalculation of laboratory results will be subject to a penalty of 10% of the score earned. Punctuality matters, too: results submitted after the due date and without an approved excuse will be subject to a penalty of 2 points per business day late.Credit will not be given for any work submitted after 4:00 PM on 22 May 2008.

Laboratory notebooks will be evaluated for  proper recording of experimental results, presentation of data, calculations and results, as well as neatness. Notebook checks will be carried out during the weeks indicated.

Expt. No.  Points Possible Title of Experiment
1
25 Acid-Base Titration with Computer Analysis
2
20 EDTA Titration of Ca and Mg
3
20 Coulometry
4
20 Iodometric Determination of OCl in Bleach
5
20  Spectroscopic Assay of Aspirin
6
20 Spectroscopic EDTA Titration of Cu
7
20  Turbidimetric Analysis of Sulfate in River Water
8 20 Two-Component Spectroscopy
9 20 Spectroscopic Determination of Fe
10 20 Gas Chromatography
11 20 Cu by Ion Exchange Chromatography


Notebook Checks: 25 points

Scoring reflects preparation and performance in the laboratory as reflected by the presence of expected
information, the answers to pre-lab assignments and the general organization and neatness of the notebook.

Two checks will be conducted during the weeks of:

3/24/08 10 pts
5/5/08  15 pts

Lecture:  250 points

Homework
Each week, 8 problems will be assigned, from which 2 are selected and graded. Fully worked s
olutions (not just answers!) are due to the mailbox or office of your Laboratory TA by no later than 1200 Wednesday of the week following the assignment. Note that the homework solutions will not be graded if fewer than 4 of the 8 assigned problems are submitted or if the assignment is submitted late, without an approved excuse. Each problem graded  counts 4 points toward your homework score. Full credit is given if a correct solution is provided and partial credit may be assigned if warranted by the work submitted. The total number of homework points (there are 96 possible points) is then adjusted to a maximum of 100 points by a scaling factor (100/96).

Mid-term Exams
Scoring  here reflects student performance on assigned homework sets and on three closed-book examinations covering all course material assigned or due previous to the examination.
The exams include definitions of terms, calculations, short answer questions and explanations of observations. General formulas, tables of electrochemical potentials and periodic tables, and all necessary physical constants are provided with the exam. Partial credit is given.

The scores from the homework and the three mid-terms are averaged as indicated below. The average is the added to the quiz score and the score on the final exam to determine the points earned in the Chem 120 lecture.

Clicker “Quizzes”
Each week, there will be a series of questions asked in lecture. You will be expected to repond to these with your “clicker” and your answers will be tabulated and scored. A score of 50% or higher on these questions will earn full (100 points) credit. Scores below 50% will receive credit in proportion to the score earned. Thus, a 40% correct scores 80 points.

Final Exam
The final exam in Chem 120 is a 2-hour, “open-page” comprehensive exam covering the lecture and laboratory work done for the course. The date and time of this exam will be set in December by the University Registrar. Up to date information on dates, times and locations of S08 final exams can be found at http://www.udel.edu/exams .

Students may bring a single 8.5″ x 11″ page with any information believed to be helpful for the exam, entered on both sides of the page. On this exam, statistical and periodic tables and all necessary physical constants will be provided, but general formulas will not. Partial credit is given. This exam is scored from 50 points.

Course Policies:

Attendance and Excused Absences Policy

The syllabus provided is approximate, and the lectures in Chem 120 may deviate from the schedule provided due to weather or to address student needs and preparation. Though attendance is not formally taken at lecture and much of the lecture material may be made available as pdf files for download, you are expected to attend all scheduled lectures. Chances to answer clicker questions can not be provided outside of lecture, and information provided in lecture may not be duplicated on the class web site. You will be responsible for information provided in lecture. Attendance at discussions and laboratories is also expected; students may not write up laboratories that they did not attend, except with the written permission of Prof. Brown.

The class policy on absences follows the University policy, which can be found in the section on academic responsibilities (page 55 and following) in the current University Catalog. Any absences from exams should be announced to the course instructor, if possible, by e-mail in advance of the exam, and the student missing an exam will generally be required to provide an excuse note to be offered a make-up exam. Absences from laboratories will be excused for medical reasons (serious illness requiring a doctor’s care), family emergencies, some University-sanctioned events, and for employer-required absences. Scheduled absences must be made known in writing to the course instructor in advance so that arrangements can be made for adjustment of due dates of class and laboratory assignments. Scheduled absences may require an e-mail from the Dean’s Office or from the employer to support student claims.

There is no makeup of clicker questions included as a part of class lecture.

Minor absences may be excused at the discretion of the course instructor (but not a course teaching assistant!) on a case by case basis, depending on the reason for the absence and what course material is missed.

Clicker Question Policy:

Each week, there will be several clicker questions embedded in the lecture. Your resonse to these questions will be recorded and the percentage or correct answers will determine the clicker score you earn for the class. The score is determined as follows: any percentage of correct answers of 50% or higher earns 100 clicker points. Scores between 0 and 50% earn a corresponding fraction of the 100 points. A percentage of 0% earns 0 clicker points.

While consultation and collaboration between students is encouraged in answering the clicker questions, use of any clicker other than your own to answer Chem 120 clicker questions is considered a violation of academic honesty.

Homework Policy:

Each week  8 required problems are assigned on WebCT.

Full solutions to these (not just answers!) are due to your TA on Wednesdays, 1 week after they are assigned.

You are encouraged to work together on the homework, but you must turn in your own set of solutions.
Identical sets of solutions will be graded and the score will be divided among the number of identical submissions.

Each set is due on Wednesday by 1200 (Noon) to your TA’s mailbox (on the left in Rm BrL) or to your TA’s office. Solution sets will be made available for access/download later that day.

Warning! No homework papers will be accepted after the solutions are made available.
Any set that
attempts fewer than 4 of the 8 problems may not be graded.

Homework will be graded by your TA as follows:

 2 problems from each assigned set will be selected by Prof. Brown “at random,” and your answers to these will be scored as “right,” “partly right,” or “wrong.” For each “right” you receive 4 credits, for each “partly right,” you receive 2 credits. “Wrong” answers receive 0 credits.

Your homework will be assigned a % score according to the number of the total possible credits and the total credits you have earned. The % score from the homework will be averaged with your 2 mid-term % scores.

Any assigned homework due prior to an exam and whose solutions are posted before the exam is considered eligible for inclusion on the examination.

How to Turn in Homework and Labs for Grading:

Homework

Homework assignments can be word processed and printed or be done in pen or pencil, on any standard paper. You should turn in homework to your TA, not to the course instructor. You can turn in your homework personally, at office hours or at the TA’s office. Or you can turn your work in to the TA mailbox in Room 105 of Brown Lab. In either case, be SURE that you have your name, your course (that’s CHEM 120), your section (that’s a number from  020 to 021) and your TA’s name on ALL pages, using the upper right hand corner of your homework. Make these legible, please. You can also put “page x of y” on each page, where x and y reflect which page this is (that’s the x) and the total number of pages (that’s the y). Pages do get separated on occasion. Then, securely staple the homework.

If you must turn in homework to your TAs office, please don’t just stuff it under the door! Be sure that it goes on the TAs desk or is placed so that it won’t get removed and discarded, or otherwise overlooked. It is best to give it to your TA personally.

If you turn in homework to your TA’s mailbox in BrL 105 (and be warned – the door is locked at about 1630!), please be careful to get the correct mailbox. The TA mailboxes are on the left as you enter. The name label is above the box, not below it. Several TAs share a mailbox, so make sure that you have labeled and securely stapled your work as described above.

Lab Reports

Chem 120 lab reports are to be done on the report forms available on the WebCT class site. These reports should be completed in pen or should be word-processed. You will turn in Chem 120 lab reports, when due, to your TA at the start of your lab in 106 Drake Hall. You will never need to turn in your laboratory notebook. All notebook checks in Chem 120 will occur in lab, so your lab notebook will never leave your possession.

Disclosure of Chem 120 Scores and Grades:

Your TA will return your graded lab reports, homework and mid-term exams. All graded material will be returned at the start of your discussion section. They will generally be returned the week after you submit them. While you can ask the TA or the course instructor about your Chem 120 scores throughout the semester, and can see your scores then, you can get Chem 120 final course grades only from the UD Registrar – neither the instructor nor your TA can release them to you by personal contact, or by phone or e-mail. No scores or course grades from Chem 120 will be released by the course instructor or TA at any time to parents, relatives, friends or others, including other UD departments or programs.

Special Accommodations:

Students requesting special accommodations in Chem 120 must already be registered with UD’s ADA Center or Academic Enrichment Center, as appropriate. Those students should contact the course instructor well in advance of any course activity to arrange for special accommodations that follow the terms of the arrangements set by the Center staff.

Academic Honesty:

University policy concerning possible breaches of academic honesty is found in the current Undergraduate Catalog (p 55 ff) and in the on-line Student Guide to University Policies. You are encouraged to become familiar with The University’s Policy of Academic Honesty  found in the UD Student Guide.  Policies delineated in the Student Guide apply to this course.  Except for responses to assigned class homework and any laboratory work done on laboratory experiments where you are asked to work in pairs or threes, all written and experimental work in the laboratory and in the classroom examinations for Chem 120 is to be done independently. You may not give help to or receive help from others on exams. While collaboration and discussion is encourged for in-class clicker questions, submitting answers to in-class clicker questions for others by use of their clicker is a violation of academic honesty. By turning work into the instructors of this course, you acknowledge being made aware of the academic honesty policy and affirm your awareness of and compliance with the policy.

Safety:

You will receive instruction in laboratory safety and chemical hygiene, and you are asked to follow the guidelines given during that instruction. We take your safety in laboratory very seriously. You are expected to do your part to ensure a safe laboratory. Please note carefully that any major safety infraction  – such as failure to wear safety glasses as required – is grounds for expulsion from the laboratory for the period in which the infraction occurs. Any work not completed as a consequence of an expulsion cannot be made up or repeated.

Seat Claim Policy:

Because of the limited number of spaces in Chem 120 labs, this course follows the Seat Claim policy established by the Provost’s Office and outlined in the UD Catalog: anyone missing the first two classes or  laboratory sessions is regarded as relinquishing his/her claim to a seat in this course. Further, those students registered for Chem 120 but not claiming a seat and not completing the drop process may receive a “Z” grade for the course. Attendance will be taken within the first 30 minutes of each laboratory at the beginning of the semester.

E-Mail Policy:

Important notices and correction of errors will be sent to the UD e-mail distribution list for the class to provide the fastest dissemination of the information. The registrar will include your campus e-mail account on these class distribution lists, so plan to check it regularly.

Course personnel make every effort to respond promptly to e-mailed questions or concerns from students, but turnaround is not always immediate, so please plan ahead.

Cell Phone Policy:

Placing and especially receiving phone calls or text messages in class is disruptive and discourteous to your fellow students and to the course instructor. You are expected to turn your cell phone off and stow it during lectures, labs and course help sessions.

Accessing a cell phone, pda or ipod during any Chem 120 exam is a violation of academic honesty and may result in the immediate expulsion of the student from the exam.
