Physical Methods in Chemical Analysis, Volume II discusses analytical procedures that deal primarily with nonchemical methods and techniques useful in establishing the qualitative nature of unknowns. This book discusses electrical, magnetic, and miscellaneous techniques, including a number of methods that only measure non-specific properties to obtain quantitative information on relatively simple systems such as conductometric titration and radioactive tracer methods. This volume emphasizes two major tasks that analysts need to do in order to perform analysis. First is to conduct preliminary operations that bring the system under investigation into physical states suitable for analysis. Second is to measure physical constants that can be compared with known systems for identity or can be interpreted in terms of structure and organization. This publication is a recommended reference for students and chemists working on chemical analysis.
