Query: What do you expect?

This is an analytical chemistry textbook, not exactly the most thrilling of chemical disciplines. (unless you are an analytical chemist). It explains things fairly well, and the problems are at the end of the chapters are pretty similar to what you would find on the ACS test for analytical chemistry. The author has a sense of humor and randomly inserts jokes in some of the material. I believe this is the most popular of textbooks for analytical/quantitative chemistry courses.
