This lab manual was designed for use in the General and Quantitative Analytical Chemistry courses (CH109/110) at Boston University. The topics introduced in these labs include many of the fundamental concepts that are ubiquitous to the general chemistry curriculum: gas laws, solubility reactions, acid/base chemistry, spectroscopy, thermochemistry, equilibrium, and kinetics. Additionally, quantitative analysis adds an emphasis on experimental design, statistical treatment of data, advanced topics in spectrophotometry, critical thinking, scientific communication, and research.
The goal of this course is to provide general chemistry students who have already had a significant level of exposure to chemistry, either in high school or college, with the opportunity to become familiar with common instrumentation and develop good analytical techniques.
