Textbook: Daniel C. Harris, “Quantitative Chemical Analysis”, 8th ed.
A study of the fundamentals of analytical chemistry. Students in this course learn how to use physical measurements to make quantitative chemical measurements reported with defined uncertainties. Concepts of chemical mass and charge balance are used to calculate chemical speciation in complex acid/base and redox systems. Lectures and homework focus on problem solving skills that provide solutions to new problems based on fundamental chemical principles and constants. The required laboratory introduces students to advanced volumetric, potentiometric and spectroscopic techniques for quantitative chemical analysis. Written lab reports reinforce the technical writing style used in chemical communications.

The Homework is a very important component of the course. Homework will be assigned every week. Answers to the homework are provided in the back of the book. Your job is to work out the solutions that yield the answers. All homework will be graded and should reflect your own knowledge of the problem.
Many problems will be best solved using a computer program/spreadsheet. Include a hard copy of the results with your homework assignment and also place the program/spreadsheet used to solve the problem into your folder on the file server. You should have your own backup copy of your homework!!! You will be allowed to use some of your computer programs to solve problems during hour exams.
Prelab exercises are an important component of the laboratory. The prelabs familiarize you with the current week’s experiment making you more efficient in the laboratory and often improving your results. A short lab quiz will be given before each new lab exercise.
All students are expected to do their own work. In some cases I will ask you to work on experiments in small groups. I expect and encourage you to discuss the procedures and results of these experiments with your fellow classmates. It is also acceptable to work together on difficult homework assignments. However, the final lab reports and completed homework assignments should be your own work. This means that you should be able to explain in detail all of the steps and procedures used to solve a particular homework problem or lab assignment. All spreadsheets should be your own work, including the equations! If you work with other students on homework or lab assignments you should acknowledge this collaboration by listing their names on the top of your assignment.
