The parent, edition was somewhat of a departure from a traditional quantitative analysis text-both by the types and depth of matter included. The authors in their desire to produce a. less rigorous text have accomplished their goal; however, in so doing have created a text, that has last much of its earlier citement" or advantages. Both texts are adequate for s. one-semester quantitative analysis course, with the expanded version still not suitable for a separate tev instrumental-type eourse. With this last point in mind a11d the difference in price being only a few dollsrs, the reviewer prefers the parent edition. The tional subject matter providesmuch better of the material and allows the instructor greater versatility in planning his course.

A rigorous and detailed examination of the thermodynamics of metal complex formation provides the leitmotif for this massive, mholal.ly contribution of two Israeli seientifit,~in which the complementary techniques of solvent extraction and ion exchange are described. Marcus and Kert,es, themselves active researchers in these fields, provide a firm foundation for the thermodynamic aspects ,of t.he two important separation techniques in the first quarter of their hook where, in three chapters, the t,hermodynamics of aqueous and non-aqueous eleotrolgte solutions are presented. Thorny prohlemn snch as the quantitative consideration of concentrated and mixed electrolyte aqlleous salutiona as well as mixed solvent and aggregation (including micelle formation) in organic solvents are presented and dealt with in a competent, "present state of the art" approach. The mathematical appamtufi for dealing with complex formation equilibria with particr~lar emphasis on the delicate decisions required to distinguish hebween true complex formatiall and J. M. PAPPENHAGEN"lreachemu~" activity effectsis presented. Kenym College After a chapter dealing with ion exGambier,Ohio changers, ttheir swelling and sorption
equilibria, as well a5 exchange phenomeua occurring in concentrated solutions and mired solvents, there follows twin chapters dealing with the many ramifications of the use of cation and anion exchange to determine the equilibrium constants of metal complex formation. The use of solvent extraction in stndying metal complex equilibria receives a similar treatment. The authors organize extraction systems inio the following categories and devote a chapter to each: Extraction by (1) compound formation (chelates, acidic organophosphorus compounds, salts of earboxylic and sulfonic phosacids), (2) solvation (carbon-r phorus-bonded oxygen-donor solvents, (3) ion-pair formation (use of quaternary ammonium, phosphonium, and xrsoninm salts), and (4) syuergism (mixed ligand systems). The hook is well organized and each of the twelve chapters has a detailed summary of the viewpoint and the content of the text material. There are occasional examplea of the need far better integration of the material in various sections of the hook. For example, after a, fourpage exposition on the nature and use of the solubility parameter the aothars repudiate the validity of its u w with "polar" substances. Later in the text, however, solubility parameter considerations are freely employed. Again, in the section on dithisone they espouse the outmoded and incorrect Fischer stmcture of primary chelates (involving only nitrogen-metal bonding) despite their

This inexpensive book consists of fifty-five reactions involving a great variety of types for which the stndent is to wo1.k out suitable mechanisms. Few of the problems can be solved simply by inspection. The student can check his answers against the answers provided. Far the first twenty answers detailed remarks are given while for the last thirtyfive, the mechanisms are presented without comment. In addition, a lit,erature reference from which the reaction and/or reaction meehsnism wits taken is given for each problem. This book is not. designed for the beginning organic stndent to use as he progresses throogh his fin1 organic course.
