Determination and use of stability constants

Determination and Use of Stability Constants, by A.E. Martell and R.J. Motekaitis, VCH, Weinheim, 1989, 216pp. Price: DM 74.00. In the past the calculation of stability constants has been a laborious task. Indeed, from a desire to fit experimental data to curves some of the derived information has been meaningless. Today, through the use of computers, many of the problems have been resolved, provided that data of high quality are used in the computations. The measurement of stability constants is reviewed and various pitfalls are identified, e.g. inaccurate measurement of p[H]. A number of examples for the determination, !'~y potentiometric methods, of stability constants in simple and complex systems is described. Thrnughout this book the authors emphasise the need to select reliable experimental data when attempting to derive stability constants. In natural environmental systems, at the very most, we probably only have data for about 5% of the total number of stability constant required in order to describe the complex metallic-organic types of speciation which ¢~:~, hence a need to estimate the most important unknowns. Protocols for the calculation of stability constants of complex species in environmental systems are presented. This book also contains a computer disc (5 inch diskette, IMB PC compatible) for calculating stability constants and for using them to calculate concentrations of molecular species in solution.

Computer Applications in Chemistry, by K. Ebert, H. Ederer and T.L. Isenhour, VCH, Weinheim, 1989, 724pp. Price: DM 98.00. In writing a book on computer applications in chemistry the authors set themselves a formidable task. This book will clearly be of considerable interest to university students and requires an understanding of mathematics and chemistry at degree level. It is not a cook book, and requires reading from cover to cover in order to derive most benefit from its contents, Most of the chemical calculations concern classical concepts, albeit that the underlying principles have many applications in the applied field. The manner in which basic computer programmes are developed is clearly presented, but perhaps the choice of examples could have been more imaginative? Considering the range in subject matter the contents would probably attract wider interest if they had been published in a form to cover separate applications in physical, inorganic, organic and analytical chemistry. Computer programmes are
