reviews Analytical Chemistry: Principles, Second Edition John H Kennedy. Saunders College Publishing: New York. NY 1990. xvi + 936 pp. Figs. and tables. 17.8 x 24.2 cm. The second edition of Kennedfs text for undergraduate analytical chemistry is, for the most part, similar to the first edition. This edition maintains the author's emphasis on the "total analytical process", which will he useful for helping students understand the progression of a chemical analysis problem. The text wnsists of three major sections. After an introduction to statistics and a review of equilibrium and stoichiometric principles the classical gravimetric and volumetric methods are dism s e d . The dsssical analysis section presents a g a d treatment of acid-base, complexometric, and redox equilihria. There is a small decrease in the amount of space devoted to gravimetric analysis, hut the essentials and the necessary number of examples and problems are retained. This section is well written with examples that illustrate the principles to students. There is a discussion of acid-base titrations in nonaqueous solvents and an alternative method for solving problems on sulfide solubility in acids. An ap~ e n d i xis included that has comouter woerams written in BASIC ior solving some of the solutioh eqi1ib;ia problems. Given the prevalence of simple spreadsheet methods for solving these types of problems the appendix probably will serve simply a s an example of programming approaches to the problems. The next section involves an introduction to some instrumental methods in chemical analysis. This section covers spectrochemical, electrochemical, and separation methods. A new section has been added on kinetic methods of analysis that provides an introduction to the basic wncepts hehind kinetic approaches. In this chapter a discussion of neutron-activation analysis and enzyme-catalyzed reactions is covered. The main text concludes with two chapters that were not in the f r s t edition. One nice addition is a chapter on sampling. The statistics of choosing an appropriate sample and sample size are discussed along with sampling methods for various physical and chemical situations. The last chapter is an overview of laboratory techniques. The third section is an auxiliary lab manual. The lah manual is similar to the first edition with the addition of two new experiments (one on the determination of A1 in chewing gum by graphite furnace AA and the other on the determination of caffeine in soft drinks by HPLC). The lah manual is an accompaniment to the text with 59 experiments for determining various elemental and m+ lecular species in a variety of common (often household) matrices. Overall, Analytical Chemistry: Principles and Practice is well organized and clearly written with many interesting examples. Students should fmd this text easy to follow, and the accompanying lab manual will help their lab experience.

The volume includes a 6-114 page informative and inspirational essay, "The Joy of Teaching Chemistry" by Doris Kolb, editor of the Journal of Chemical Education's "Overhead Proiector Demonstrations" series. This well-planned, attractive, and oversized volume contains 48 demonstrations, including 78 separati, procedures, all tested at the University of Wisconsin-Madison and elsewhere, ranging in length from 2-1/2 pages ("Bromate Oxidation of Manganese," pp 83-85) to 11.113 pages ("Copper Leaves: Electroplating with Copper," pp 212-223). They are gmuped into two chapters-Chapter 10, "Clock Reactions," 15 demonstrations, 87 pp, and Chapter 11, "Electrochemistry: Batteries, Electrolytic Cells, and Plating," 33 demonstrations, 179 pp, each prefaced with detailed introductions (11 and 7 pp, respectively) featuring much valuable background material. Shakhashiri's excellent five-page introductory discussion of pedagogical principles, effective presentation of chemical demonstrations, and practical advice on how to use the hook is reprinted from Volume 1. The 2-113 page list of sources has been updated through 1991. Each demonstration is divided into seven sections-41) a brief description; (2) materials; (3) procedure, subdivided into "Preparation" and "Presentation" subsections; (4) hazards; (5) disposal; (6) discussion (often elaborate); and (7) references. Perennial favorites are included, such as the Landolt Iodine Clack, old Nassau reaction, the electrolysis of water and various salt solutions, the mercury beating heart, the Daniel1 cell, dry cell, fuel cell, and the preparation of metallic mirrors, hut often with elaborate and ingenious variations.
