COURSE OUTLINE
I. Catalog Description
CH246--Quantitative Analysis
C-3,P-4, Cr 5
Prerequisite: CH141 General Chemistry 1 and CH142 General Chemistry
2.
This course introduces analytical chemistry and develops the skills and
perspectives necessary to solve problems. Topics include sampling,
gravimetry, titrimetry, stoichiometry, equilibria, redox, potentiometry, and
spectrophotometry. . Samples are chosen to illustrate typical industrial
and environmental problems. As time allows, field trips supplement the
campus experience.
II. Texts and Laboratory Materials
Text: Analytical Chemistry, Gary D. Christian, latest Edition, Wiley
Publishing
Laboratory Supplies
Laboratory Notebook
III. Student Learning Outcomes
Upon the completion of Quantitative Analysis, the students will be able to:
1. Demonstrate an ability to work in a laboratory safely and efficiently.
2. Demonstrate an ability to maintain a notebook.
3. Demonstrate an ability to follow procedures to the letter (protocol).
2
4. Write chemical reactions to explain experiments.
5. Prepare solutions correctly.
6. Demonstrate the necessary calculations of analytical chemistry.
7. Communicate in written reports on the work.
8. Discuss the literature of analytical chemistry.
9. Demonstrate responsibility for their actions.
10. Explain in words the key importance of analytical chemistry to
industry, environment, and clinical chemistry.
IV.
General Topical Outline
Lecture topics should be chosen to correlate as closely as possible with
the laboratory and to supplement and extend the practice. Individual
instructors may choose to meet these and the general course objectives in
different ways. The following is a recommended outline. In general, the
theory should follow the practice in order that students can more clearly
see the application.

QUANTITATIVE ANALYSIS LABORATORY SCHEDULE
The laboratory is where the student applies the knowledge gained from the
lecture and assigned readings to actual practice. The success of the course
depends directly on the laboratory experience. Lecture is designed to support
and extend the laboratory. The text describes procedures in a general way. It is
up to the student to make decisions as to how the work is carried out. Major
emphasis is placed on accuracy and precision. A suggested laboratory
sequence follows. It should be pointed out that many experiments require long
waiting times. Efficient use of laboratory time requires that students be able to
proceed to the next experiment in such cases. In general, a new experiment
should be introduced each week and students allowed to proceed through them
at their own pace.

Note 2
Make-Up, lab Practical, Check-Out
Note 1: Experiments during Weeks 12 - 15 require special equipment. Students
should cycle through these in a Round Robin sequence to insure hands-on
experience with the instruments for each student.
Note 2: In general, students will continue into CH229, Chemical Instrumentation,
and should keep the same assigned lockers. Exceptions should be rare enough
to take care of informally in terms of the Checkout. The lab practical can be
made a part of the final exam.
