Analytical Chemistry, Second Edition covers the fundamental principles of analytical chemistry. This edition is organized into 30 chapters that present various analytical chemistry methods. This book begins with a core of six chapters discussing the concepts basic to all of analytical chemistry. The fundamentals, concepts, applications, calculations, instrumentation, and chemical reactions of five major areas of analytical chemistry, namely, neutralization, potentiometry, spectroscopy, chromatography, and electrolysis methods, are emphasized in separate chapters. Other chapters are devoted to a discussion of precipitation and complexes in analytical chemistry. Principles and applications and the relationship of these reactions to the other areas are stressed. The remaining chapters of this edition are devoted to the laboratory. A chapter discusses the basic laboratory operations, with an emphasis on safety. This topic is followed by a series of experiments designed to reinforce the concepts developed in the chapters. This book is designed for introductory courses in analytical chemistry, especially those shorter courses servicing chemistry majors and life and health science majors.
