Housecroft and Constable - Chemistry (This advanced undergrad book covers all aspects of chemistry fairly well, with worked examples, and is good for review).

General Chemistry is the same as AP Chemistry. This is where you start if you never took a chemistry class, or only took high school chemistry. Harris is the golden standard of analytical chemistry. A basic knowledge of statistics and excel will help.

Again, it is important to do the problems at the end of the chapters.

Harris - Quantitative Chemical Analysis.

Skoog, Holler, and Crouch - Principles of Instrumental Analysis.It's not difficult if you know the concepts and do practice problems. The best book for introductory Organic Chemistry is Klein.

Klein along with his 'As a Second Language' series will give you enough problems to keep you occupied for days on end. Clayden, Greeves, & Warren is probably the best for those serious about chemistry. Reading it along with Klein would be a good idea. Wade is also a good supplement for an introductory book.
