This hrief monograph is designed as a supplement for 8, general chemistry course in which the teacher desires to present t,he subject of chemical equilibrium mare rigorously than the treatment in a. typical general chemistry textbook. An introduction to chemical kinetics and thermodynamics provides the basis for the presentation of the concept of equilibrium. After a. general discussion of the subject the following types of equilibria are h a t e d in some detail: acid-base, complex ions, solubility and oxidat,ion-reduction. The method of charge balance and mass balance is used in solving for equilibrium concent,rations. Log concent,ration versus pH diagrams are used extensively in the chapter on homogeneous equilibria. The plots and illustmtions given thmughaut the book are very helpful in clarifying the subject matter. Much of the book is mathematical in its aporoach. Problems are given at the end bi each chapter in order to provide drill for the reader. The answers to these problems appear in the appendix. The treatment of the subject matter is thorough and ~roeeedsfrom the simple to the more complex. I n addition to it,s usefulness as a supplement in a general chemistry course, the book is excellent for self-study for anyone who wishes to sharpen his understanding of the fnndamentals of chemical equilibrinm.

This text introduces both principles and pract,iee of physical organic chemistry with interesting and important lahoratory experiments. Instrumental methods such as glpc and esr, nmr, ir, and uv spectroscopy are freely used as tools for studying basic principles of organic chemistry. Experiment 1, for example, deals with measurement of the relative reactivities of benzene and toluene in electrophilic substitution reactions and calculation of partial rate factors. Some of the many topics covered are: Hammett rho-sigma. linear free energy treat,ments, determination of kinetic order, deuterium isotope eflect,s, cryoscopie evidence for formation of carbonium ions in sulfuric acid, kinetic in^ and product evidence for neighbor group heats of reaction,

kinetic and thermodynamic control of a reaction, properties of the naphthalene anion radical, and asymmetric indoction. The section of this laboratory text on chemical prepsratians contains synthetic procedures of ~tnusual and current interest. For example, syntheses of !3,!3dimethylstyrene by the Wittig reaction, preparation of A1,%ctalone-2 from o y c b hexanone by condensation of the pyrrolidine enamine with methyl vinyl ketone, and preparation of dichloronarcarene fmm cyclohexene and dichlorocarbene, and of tryptycene from beneyne and anthracene are included. Each topic has a deer and concise development of the theory behind the ex~ e r i m e n t references , to the original literature, and supplementa~yproblems. This book deserves serious considerntion as a manual for advanced laboratory courses and s*i a reference text on experimental methods in ~hysicalorganic chemist~y. STANLEY G.

This book is an %bridged version of the third edition of "Quantitative Chemical 46,A196 (1969)). Analysis" (THISJOURNAL, It is significant to note that this new version was essentially prepared by deleting sentences, paragraphs and pages and not (with only a few exceptions) by condensing any of the material in the parent edition. Nearly 350 pages of subject matt,er have been removed; yet the aame basic format of chapter and material presentation has been retained. Examples of reductions in material include the following: two chapters on electrochemical methods of snaiysis (135 pages) have been merged into one such chapter (43 pages); material in a separate chapter on acidbase reactions in nonaqueous solvents (38 pages) is now shortened to 7 pages and included in the chapter on acid-base titrations; chapter on chemical equilibrium shortened bv 24 pages: chapter on separations shortened by5'page;. spacedoes not permit the listing of topics that have been omitted, hut as stated in the Preface, "many of the discussions here are less rigorous and some of the advanced and specialized topics have either been eliminated altogether or reduced t o hrief descriptive statements." I n excess of 30 figures and tables have been omitted, a3 has an excellent table in the appendix on Standard and Formal Potentials for HalfReactions. The abridged text contains 5 fewer laboratory experiments (4 titrimetric, 1 colorimetric). The remaining 27 experiments are identical wit,h those found in the parent edition. The questions and problems a t the end of each chapter are reduced somewhat. in number (Calinued on page A136)
