General Information

• Text: Daniel C. Harris Quantitative Chemical Analysis 4th Edition, W. H. Freeman and Company, New York 1995 (required)

• Course Content: This is a lecture course addressing aspects of modern chemical analysis with an emphasis on chemical equilibrium.

• Course Objectives: The objective of this course is to introduce the student to fundamental concepts of analytical chemistry with particular emphasis on quantitative analysis. The theories, concepts of experimental design, and data analysis as they apply to quantitative analysis will be discussed. There is particular emphasis' placed on the concept of chemical equilibrium and chemical thermodynamics and on calculations.

• Lectures: Lectures will cover basic statistics, chemical equilibrium, gravimetric analysis, volumetric analysis, acid-base chemistry, complexation, spectrophotometry, and separations.

• Examinations: There will be two in class examinations, each worth 100 points, and a final examination worth 150 points. Problems at the end of each chapter in the text will be assigned. These problems should be worked for your own benefit. Homework will not be graded but the successful student must work through them. The examinations will be based on the assigned problems. The test questions may be taken from the homework verbatim, or may be altered to have different numerical values or reagents. Questions can be synthesized from several homework problems.

• Grading: Grades will be based exclusively on your performance on these three examinations. Point scores will be added and a percent score calculated. The guaranteed grade cut-off of 90+% A, 80%-89% B, 70%-79% C, 55%-69% D will be used. +/- scores will be used as prescribed in the Undergraduate Catalog. The percentile scores may be adjusted, only upward, to curve the percent scores if the examinations appear to be too difficult and if the class, as a whole, did not perform well on specific questions. Past experience has shown that those students who do the homework and understand what they have done will generally pass with high scores.

• Withdrawal Policy: This course will follow the University policy on withdrawals stated in the current Undergraduate Catalog. Drop dates are listed in the Fall 1997 Schedule of Classes.

• Missed Examination Policy: Students may be excused from an examination in cases of emergency. Documentation must be supplied to be excused. In cases of excused absence, grades will be assigned based on % of adjusted total score. No repetition of examinations is permitted.

• Attendance Policy: Attendance will not be taken. Attendance is mandatory for successful performance in this course.

• Student Disability Statement: Any student with a disability that requires accommodations must contact the Instructor. The disability must be documented by the Disability Resource Center. Course materials may be requested in alternative formats.

Notes

• Note on reading Harris's Quantitative Analysis: Be sure to read the Summary and Terms to Understand sections at the end of the chapters both before and after reading the chapters. I have found that it helps me weed-through some chapter since the forest is often difficult to see on because of the trees. Please read the chapters prior to coming to class for the lecture. Your questions may then be more properly addressed.
• Note on mathematics: Algebra is absolutely required for this course. A successful student will be proficient at manipulating equations by the middle of the quarter. Think of algebra as fun!?. There is great satisfaction in obtaining a symbolic result for a complex system.
• A note regarding Chemistry 361 laboratory: Quantitative Analysis II Laboratory is graded separate from lecture. Laboratory performance does not influence lecture grade, or visa versa. Laboratory manuals will be available in the Taggert Student Union copy center. You need to have a manual before coming to the first class since it contains the check in list and the safety agreement. A bound laboratory notebook is required. Students taking the laboratory should read Chapters 2, 25 and 26 in Harris. Pay particular attention to the use of analytical balances, burettes, volumetric glassware, and sample drying.
