Required text: Exploring Chemical Analysis, 2nd ed., by Daniel C. Harris.
Analytical chemists determine what chemical substances are present (qualitative analysis) and how much of each chemical species is present (quantitative analysis). The objective of this course is to present methods of quantitative analysis that may be used in the accompanying laboratory course. A minimum of new chemistry will be introduced, but the chemistry learned in previous classes will be looked at in light of using it to determine the amount of materials present.
The lecture schedule is given below. Exam dates will be announced in class at least one week before the exam and will cover the indicated material. The first exam will contribute 30% toward the final grade. The final exam will contribute 50%. Since this is primarily a course about the laboratory, the last 20% will come from your grade on the final laboratory experiment which will reflect your understanding of this lecture material. Some lecture time toward the end of the semester may be available for this laboratory work.

Required text: Exploring Chemical Analysis, 2nd ed., by Daniel C. Harris.
Analytical chemists are concerned with a wide spectrum of measurements and separations. The analytical chemist must appreciate the measurement requirements of both major and minor constituents at the macro and micro levels. She must recognize the importance of statistical evaluation of sampling and sample measurements. In addition, the analytical chemist must also appreciate the additional requirements for speed and adaptability to new technology.
In CHE311L the experiences are intended to provide the student with an opportunity to:
a) learn basic techniques of accurate chemical measurements,This is a skills course. You should use this opportunity to familiarize yourself with as many of the chemist tools, and techniques to use those tools, as possible.
b) develop confidence in their ability to make accurate chemical measurements,
c) develop the ability to evaluate and interpret accurate chemical measurements,
d) develop the ability to recognize the "big picture" and sort out which chemical measurements are critical to properly resolving a problem.
Students will individually perform each experiment and write individual laboratory reports. Discussion among students is, however, encouraged.
All students should be familiar with laboratory safety rules. In this lab many strong acids and bases as well as other highly corrosive or toxic substances may be used. Wearing aprons and other protective clothing is encouraged. If in doubt, ask.
The following experiments from your text are required and should be done in the order given. Each determination should be repeated at least three times (four times is suggested) in order to do a statistical analysis on the data.
In addition to these required experiments, one additional experiment should be chosen as a final project. This final project will also contribute toward the lecture grade. Be sure to choose this early and get with the instructor in order to have the necessary chemicals and equipment available.
Laboratory reports for each experiment will be individually handed in and graded. The hand-out "Chemistry Laboratory Reports" outlines the format and contents of these reports. The relative weight toward your report grade, for each area of the report, is given as percentages after each major heading. Notice the importance of recognizing uncertainties and determining their influence on the reported values. A statistical analysis should be done for each experiment!
Reports should be handed in as soon after the experiment is completed as possible. Reports for the first four experiments must be handed in before progress reports are due (around 8 October).
Each of the required reports will be given a maximum of ten points toward the final grade total. The final project will count double toward the overall grade (a total of 20 points possible). The number of points you have earned will be divided by the total number of points possible to determine your grade for the course. The scale used by the school will be used to assign the grades.
