Exploring Chemical Analysis, 5th Edition, Daniel C. Harris, W.H. Freeman and Company, 2013
CEM 262 Quantitative Chemical Analysis Laboratory Manual 2014-2015 (Downloadable only from the LON-CAPA
website: http://lon-capa.msu.edu/)
Required Materials
(1)Basic scientific calculator (with the capability of performing base-10 logarithms)
(2)Laboratory notebook with numbered, bound pages (an inexpensive ~$3 composition notebook works well,
lined or quad-ruled, with the pages hand-numbered prior to coming to lab)

Course Grading
The course will be graded on what is very close to a straight scale. I reserve the right to alter the scale if I deem it
necessary, but under no circumstances will these thresholds be raised making it more difficult for you to achieve a
good grade. The overall course grade will be calculated according to the following breakdown:

Syllabus and Course Calendar
Experiments (50%)
This is a quantitative analysis course, and the grade for each experiment will be based almost entirely on the
accuracy of your results. Important keys to your success are your use of proper laboratory techniques and careful
planning. Labs are considered timed practical exams, and as such, you should work alone and not provide to, or
accept any data or results from, anyone else. You will submit your lab results on a “report card” (provided by your
TA) no later than the beginning of your recitation period on the due date for your Section (see the table below).
Cards turned in after the due date/time will be assessed a penalty of 10 points. No lab results will be accepted
after 5:00 pm on the last day of classes, Friday, 5/1/2015. No lab results will be accepted other than by submitting
the normal “report card” to your TA or to me. NO E-MAIL SUBMISSIONS WILL BE ACCEPTED.
Experiments 1, 3, 4, and 5 are worth a maximum of 100 points each. Experiments 2, 6, and 7 are worth a maximum
of 110 points each, because properly formatted graphs must be prepared with spreadsheet/graphing software (e.g.
Microsoft Excel or Synergy’s KaleidaGraph, etc.) and submitted with the report cards for these experiments. In this
way, the maximum number of points obtainable for all 7 experiments is 730 points.
You may redo an experiment as many times as you like in the allotted time, but your grade will be determined by
the LAST results you submitted, NOT by your best results. Each time you redo an experiment you must obtain a
different unknown from your TA.
You may attend only the lab session to which you are enrolled. Exceptions may be made in the case of excused absences, but only with prior approval from me – not your TA. Be prepared to provide evidence to obtain an excused
absence make-up for a lab or an exam: paper evidence of a visit to an M.D. or clinic, court appearance, etc. Also, it
is the responsibility of students who plan to be absent from class at certain times throughout the semester, due to
religious holidays or other valid reasons, to make arrangements in advance with the instructor. If a make-up exam
is warranted, the instructor retains the right to determine the content of the exam and the conditions of administration, giving due consideration to equitable treatment.
Labs begin the first week of class. The due dates for the experiments are given by the week in which they are due
per the table below:

CEM 262 — Quantitative Analysis — Spring 2015
Syllabus and Course Calendar
Important: Once the laboratory course has started, you perform the 7 experiments at your own pace. The Guideline
Dates indicated in the table above show the latest date the experiments should be started, and if these guideline
dates are followed, you should have no problem in completing the labs in the time allotted, though not leaving any
time for redoing any experiments. The Due Dates indicated for the reports for the individual experiments are not
flexible. Any results turned in after the due date will be penalized 10 points. As noted above, and if time allows,
experiments may be repeated in an effort to improve your grade, and results from the redone experiments do not
have to follow the timetable indicated above, but if they’re turned in after the Due Date, the 10-point penalty applies.
Also, no lab results will be accepted after 5:00 pm on the last day of classes, Friday, 5/1/2015. Remember: your
last results determine your grade, not your best results. You may turn in results early without penalty.
During your lab session, you must be properly attired, have appropriate safety goggles, and you must have your
laboratory notebook, or you will not be allowed to work in the lab.
Laboratory performance/laboratory notebook (5%)
Five percent (5%) of your course grade will be based upon your laboratory/notebook performance as assessed by
your TA. Your use of proper safety practices, care of equipment such as balances and pH meters, your ability to
work independently, willingness to understand and follow instructions, and proper use and maintenance of your
laboratory notebook are among the things that will be considered in the assessment of this portion of your grade.
Guidelines for your notebook (including an example lab entry) are provided in the beginning of the lab manual.
Unannounced notebook inspections will be conducted by your TAs throughout the term. Any scraps of paper
containing laboratory data will be confiscated during an inspection, or at any other time they are discovered. It
is imperative to ALWAYS properly record all of your data directly into your lab notebook.
Homework (5%)
Homework assignments and distribution of the Lab Manual will be done through the LON-CAPA system which
is accessed over the Web at http://lon-capa.msu.edu. Log on to the LON-CAPA system using your MSUNetID.
Assignments are given periodically, each of which include several problems to work. You can make as many as 99
attempts to solve each problem; grading is based only on whether you answered the problem correctly and the
number of attempts it took you makes no difference. The goal is to require you to get practiced in working problems
and thereby improve your problem solving skills.
Recitations (5%)
ATTENDANCE IN RECITATION IS VERY IMPORTANT TO YOUR SUCCESS IN THIS COURSE. TAs will be demonstrating
proper lab techniques, providing insight into the best strategy for preparing and performing experiments, and
discussing the calculations involved in reporting your experimental results. TAs will also answer questions about
the concepts presented in lectures and homework problems. Lab report cards will be turned in at the BEGINNING
of recitation on tor before the due date or they will be marked “late”, and receive the 10-point penalty. There will
be in-class assignments and quizzes to facilitate the understanding of lecture topics. Your attendance and, most
importantly, participation & performance in recitation will be evaluated by your TA and considered as 5% of your
grade.
Examinations (35%, combined)
There will be two in-class one-hour examinations, on Thursday, February 19, 2015 and Thursday, April 2, 2015.
Each of these examinations will test the course material which has been covered up to that point, and each will be
worth 10% of your final grade. No cellphones/tablets/computers, etc., may be used during an examination, only a
dedicated calculator.
The Final Examination will be on Wednesday, May 6, 2015 at 7:45–9:45 AM in Room 101 Biochemistry, and will be a
comprehensive examination on all the material (lectures and experiments) covered throughout the semester. It will
be worth 15% of your final grade.
