In recent years, there have been large developments in sophisticated analytical instrumentation directed to obtaining values of a physicochemical variable of a system depending on the type of substances present or their concentration. This book, the 24th volume in the Chemical Analysis series, shows how the rate of chemical reactions can be used as an analytical tool. Although the accuracy of a rate of reaction measurement is bound to be less than a direct measurement, it can, however, be of great help, especially in those cases where difficult separations are involved.
The kinetic equations for the case of mixtures for the whole range of concentrations, having in view their application to analytical problems, are presented in Chapter 5. The analytical differential reaction rates methods presented fall into two categories : either the concentration of some species is measured at definite times, or the whole concentration curve as a function of time has to be found. The rate constants for the reactions under study have to be known or measured beforehand and, in this respect, the kinetic method seems to be more suited to routine analysis. However, as the author rightly points out, a kinetic viewpoint can provide guidelines for the selection of reactions appropriate for analytical purposes or the selection of the correct experimental conditions for a given reaction. This point is abundantly illustrated in Chapters 6 and 8 for organic and inorganic systems, respectively. Some interesting applications are shown; for instance, Chapter 3 gives the determination of traces of activators and inhibitors of catalyzed reactions. It must be emphasized, however, that some fo the applications are given only to show the scope of a rate of reaction method of analysis, when other methods, such as, for example, V.P.C., would seem to be more direct and accurate. The book is well produced and over 600 references are given.
