Purity of the water supply is a pressing problem that will intensify in coming years. This laboratory manual is designed as an introduction to factors affecting water, and the methods used to assess water quality. Ideal for use in the laboratory portion of an introductory environmental chemistry or general chemistry course, the manual combines a careful balance of wet chemistry methods with instrumental techniques such as spectroscopy and ion chromatography. The Chemistry of Water can also be used in higher-level analytical chemistry and instrumental methods of analysis courses. Supplement: Instructor’s Manual
