This completely updated text/reference is designed to present the fundamental principles of chemistry with strong emphasis on experiments, applications and topics in engineering and the problems created by chemical processes. The three-part structure of the book (Chemistry - I, Chemistry - II, and Chemistry Laboratory) covers more advanced topics in applied chemistry including thermodynamics, polymers, fuel combustion, water treatment and environmental pollution. It can be used by practicing engineers, chemists, and scientists - or as a text in standard university courses in engineering chemistry, chemical engineering, and chemistry for engineers. Numerous experiments and applications of modern chemical theory, illustrations, in-text examples and exercises have been included.
