Pergamon Series in Analytical Chemistry, Volume 2: Basic Analytical Chemistry brings together numerous studies of the vast expansion in the use of classical and instrumental methods of analysis. This book is composed of six chapters. After providing a theoretical background of analytical chemistry, this book goes on dealing with the fundamental principles of chemical equilibria in solution. The subsequent chapters consider the advances in qualitative and quantitative chemical analyses. These chapters present a unified view of these analyses based on the Bronsted-Lowry theory and the donor-acceptor principle. These topics are followed by discussions on instrumental analysis using various methods, including electrochemical, optical, spectroscopic, and thermal methods, as well as radioactive isotopes. The finals chapters examine the separation methods and the essential features of organic chemical analysis that are different from methods for inorganic compounds. This book is of value to analytical chemists and researchers.
