Objectives: Analytical Chemistry (CHEM 247) focuses on the use of analytical techniques to
quantify the components in a sample. In this course you will gain proficiency in the following
topics:
1. General overview of an analytical process 2. Statistical data treatment 3. Acid-Base equilibria,
titrations, buffers 4. Equilibrium constants: solubility, activities coefficients 5. Chelation and the
use of EDTA 6. Electrochemistry and electroanalytical techniques 7. Spectroscopy: molecular
(UV-Vis), fluorescence, and AA 8. Analytical separations, chromatography

Evaluation:
Midterm Exams (2) 300 pts 30% Quizzes (3) 75 pts 7.5% Written report (1) 25 pts 2.5% Final
exam 300 pts 30% Laboratory component 300pts 30% Total: 1000pts 100%
Grades will be assigned as follows (there will be no curve in the class):
A > 890 pts B 780 – 889 pts C 680 – 779 pts D 580 – 679 pts E < 580 pts
Quizzes: Four quizzes (each worth 25pts), based on the homework assignments and
the Lecture material, will be given during class. The lowest quiz grade will be dropped
and the highest THREE used to compute your quiz total; therefore, there will be no
make-up quizzes.

Written report: One written report on the talk given by the invited speaker. The report
should include: a brief summary of the talk, what have you learnt, how does it affect (or
motivate) your appreciation of taking Chem 247?
Exams: Two midterm exams will be given, in class, on the days indicated on the lecture
schedule. The exams will last about one hour and will be worth 150 points each. There
are no make-up exams. If for any reason you need to miss an exam I will replace the
missed exam with the lowest score from your other two exams. The final exam will be
comprehensive and will last for at least 2 hours.
Assignments: Readings from the text and homework problem sets are assigned for
your benefit. The quizzes and exams will be based on this material, so it is strongly
suggested that you keep up with the schedule. The more problems you work, the more
proficient you will become with the material. To get ready for the exams, work additional
problems at the end of the chapter and study the class assignments, notes, and quizzes.
Laboratory Component: Detailed description on page 4.
Academic Dishonesty: Cheating will not be tolerated in this class. If a clear violation is
encountered, then all of the parties that have participated will receive no credit for that
assignment. For example, if lab reports or writing assignments from previous semesters
are copied and turned in for credit, then you will receive a zero on that assignment (FYI, the
instructor has copies of all lab reports and assignments from previous semesters). Obviously,
you are expected to have similar lab results as your lab partners, but you are expected to work
on your calculations and reports independent of one another. If your formats are found to be too
similar to other classmates, this will be considered cheating. Though cheating is often difficult to
detect, you can be sure that I am always on the lookout because I find cheating to be personally
repugnant and equivalent to stealing.
ADA Syllabus Statement: Reasonable accommodations will be made for students with
documented disabilities. In order to receive accommodations, students must obtain a
letter of accommodation from the Center for Disability Resources and make an
appointment to speak with me as soon as possible. The Center for Disability Resources
(CDR) is located in Life Sciences Room 218, telephone 312-567-5744 or
disabilities@iit.edu.

Lab Reports: Each report should be typed and have the following sections: 1) Title and Name
(along with name of lab partners), 2) Abstract, 3) Experimental, 4) Results and Discussion 5.)
Conclusions and 6.) References. Read the guide and examples that are posted on Blackboard
for the proper preparation of a report. Complete lab reports should be submitted as hard copies
on the due date at the beginning of the lab period.
Grading Policy: The lab reports will be graded on the content (how well did you write-up your
results), the results of the experiment, and the use of significant figures. Each report is worth
30 pts for a total of (8 reports x 30 pts) 240 pts. The other 60 pts for the lab portion of the class
will be assigned by the lab TA based on your lab technique and lab notebook. The lab notebook
should have a table of content. *Lab reports are due at the beginning of lab. If the reports are
late, then 10 points per day will be deducted from the grade until the report is turned in. All lab
reports, including make up lab reports, are due on Monday November 28. Make-up Labs: If
you must miss one of the labs due to illness or a school sponsored event; or have the need to
repeat the labs due to poor or incomplete results, you must contact me ASAP with the reason
for not being in lab and then schedule with the TA to do the lab during one of the make-up
periods. You must notify them in writing at least 3-days before the section, so that they have
time to ensure that the necessary chemicals and equipment are available for you when you
come to lab.
