Although this laboratory manual has been designed for a two-semester introductory course in chemistry, by proper selection of experiments it should be readily adaptable to a one-semester course. The reviewer agrees with the author that this manual should he very well suited for nonscience majors in a university, especially for students enrolled in nursing, home-economics, agriculture, liberal arts, business and fine arts curricula. It should also he suitable for a small school that offers hut a single course in chemistry. This manual has not been designed for any single textbook. The author has prepared such a selection of laboratory exercises that it should be adaptable to most available textbooks in chemistry designed for non-major students. Sufficient introductory material is introduced so that each experiment can he carried out independently from the lectures in the course using the textbook primarily as a reference source. Proper laboratory technique is emphasized throughout the manual. The correct techniques required to carry out most of the experiments are clearly illustrated in the description of the experimental procedures. The author carefully relates the laboratory experience to basic concepts and principles of chemistry, especially by requiring the student t o complete a fill-in type final report after completing a data report. There are other commendable features in this manual. Great emphasis is placed on safety and proper safety practices. To

he sure the student has read the safety rules of the laboratory, he agrees to abide by these rules hy signing and dating the page on which they appear. The author has repeatedly emphasized cautions in the various experiments, as well as the proper disposal of waste materials. For each experiment the author has prepared a pre-lab study quiz in order to induce the student to read carefully and understand the procedures and purposes of the study before he reports to the laboratory. Duplicate copies of the data sheet are furnished for each study. By the use of a carbon sheet, a duplicate copy of this report will he available for the student. This copy should prove useful to the student in the preparation of his final report on the experiment. The first 16 lahoratory studies deal with material usually contained in the fields of general or inorganic chemistry, such as basic lahoratory techniques, properties of water, hydrates, some common metals, common acid and bases, conductivity, anion analysis, chemical equilibrium, p H and buffers. Studies 17-21 and 26 deal essentially with organic ehemistry. The first three of these studies deal with organic chemistry teehniques, the next ones with typical functional group reactions, and the determination of the structure of an unknown organic compound, while study 26 describes the synthesis of aspirin, phenolphthalein, flourescein and neralin. Such biochemical studies as the carbohydrates, lipids, amino acids, peptides, proteins and enzymes are covered in studies 22 to 25. Studies 27 and 28 are concerned with blood, urine, milk and other food products. Gerald F. Grillot Syracuse University Syracuse, New York 13270

This text appears to be aimed a t twoyear college ehemistry students who have not had any prior chemistry. The presentation is largely a deductive treatment, clearly and simply written, with extensive illustrative examples and problems, with eye-catching, humorous cartoons, and with strong textual emphasis on stoichiometric calculation skills-the latter extending in one development over 100 pages. The authors' preface indicates to the student the two mathematical skills which are amply presented, the factor-unit method problem solving and instruction in the use of the slide rule. The factor-unit method once mastered by the student is a most useful skill, especially for the nonmathematically oriented. The treatment of the slide rule includes discussion of the circular slide rule, a most popular format because of its pocket size. The contents begin with a brief introduction to the study of ehemistry, briefly and deductively-the student would gain little conviction h m the half page on the scientific method. Measurements and properties of matter follow with an early introduction to the use of significant figures. Neat come atomic structure, chemical honding, and periodicity. No attempt is made here to give an historical or eaperimental basis for the modern atom. Then begins the many stoichiometry chapters, from nomenclature of compounds through mass and volume calculations by the mole method. Formula calculations, equation balancing, and mass calculations, both as textual examples and chapter-end problems, abound in these chapters. I t is surprising to see the gas laws follow the staichiometry since they lead so naturally to the mole concept. Next come chapters on solids, liquids, and solutions, on water, and on acid and base reactions. They include some calorimetry and phase enthalpy calculations but none using the enthalpy additivity principle. The next 50 pages constitute a brief treatment of many important principles: oxidation-reduction and cells, reaction rates (with a rate equation thrown in) and equilibrium, the latter including weak electrolyte and slightly soluhle salt equilibria. Entropy as a measure of disorder in a system or as a driving force far change is not treated. The hook ends with a chapter an radioactivity. Chemistry courses in the 70's seem to he focused on the environment. This book has very little to say about pollutants, their chemical reactions, analyses, and effects on materials and living things. Air pollution is relegated to three brief footnotes. The problems a t the end of chapters are long in quantity but short in approach variety with predominance on definitions, listings, classifications, and stoichiometry calculation types. The cartoon illustrations of principles and analogies are an attractive feature of the book.

The appendices, preceded by a 10-page glossary, contain exponents and notation, slide rule, isotopes, electronic configurations, water vapor pressures, logs, and a handy square root table. George F.

clear and readable style, and there is an attempt t o relate the discussion of specific topics to the principles which were developed earlier. The lecturer will probahly want t o do more of this. The text contains problems and study questions a t the end of each chapter, including some "open-ended" questions. Unfortunately for the students no answers are given even for the numerical problems. Possibly the main idea that a student using this hook will retain after the course ends is the importance of energy in chemistry, in science and t o mankind. For the nonscience student to have obtained a firm mental grasp on a t least one major concept during the course may be a sufficient accomplishment t o justify trying this textbook.

It would be appropriate for a onesemester course since it contains 16 chapters each of which can be covered in about three class periods. The first 9 chapters are strongly ariented toward physics. Concepts such as chemical solutions, concentration, chemical equilibria, groups of elements, etc., are barely described, while electrical units, enthalpy, entropy, free energy, quantum numbers, ete., are mare thoroughly considered. Later in the book about two pages are spent on oridatian-reduction and two pages an acid-base concepts. Threaded throughout the book are discussions af energy with topics ranging from gravitational energy to several pages on nuclear energy. Much of the discussion of chemical reactions is related t o the energy changes rather than to the substances inlolved. One has the impression that too many topics are introduced in these 9 chapten and many of the principles are developed inadequately to help the student acquire a good understanding of the concepts involved. Unless the students using the hook had previously had good training in physics and the early chapters were functioning as a review, it would require mast of a semester to expand sufficiently the coverage of that material. Alternatively some of the topics might be ignored in order t o explain fewer concepts and to devote more time to the last half of the book. The intent of the authors is to develop in the early chapters some principles of chemistry and physics and to show that their development was logical, but to omit, as much as possible, the "facts." Then in the latter half of the book the principles are applied to a discussion of some chemical topics to which the nonscience students can relate through their own experiences or general reading. These chapters involve the reader with the chemistry of living systems, diseases and poisons, food and nutrition, and the environment, as well as with chemical technology and energy conversion. Since this is the material which the students will find t o he of considerable interest, i t is desirable to get to these chapters as quickly as passihle and to spend a good portion of the semester an them.

This text, designed for a one-semester course a t the freshman or (more apprapriately) sophomore level, most assuredly cannot be viewed as "just another quant book", for in fact it is the most innovative treatment of elementary analytical chemistry to appear in many years. The major departure of this text from conventional practice is a generalization of "wet" methods, avoiding the usual classification by "reaction type" (acid-base, redox, etc.). Instead, following several introductory chapters, the authors deal with aqueous acid-base, silver halide precipitation, redox, and EDTA titrations in a single thirty-page chapter (Volumetric Analysis in Aqueous Solution). By so doing, €he authors minimize the redundaey which usually results when each of the common "Sshaped titration curve methods" is treated as a distinct entity. Following the Volumetric Analysis chapter (which, for many instructors, will be the heart of the text), appear two superb chapters on solvent effects upon acid-base reactions and ionic equilibria in general, two excessively detailed chapters on the shapes of titration curves end errors in titrimetry, one chapter on indicators, and a final chapter dealing with Instrumental Analysis of Liquid Solutions. A second section presents laboratory instructions and experiments. Efforts to generalize the presentation of traditional analytical chemistry are long overdue; an instructor of introductory analytical chemistry can hardly fail to ohtain many new ideas for his own course by carefully perusing this hook. Whether i t will succeed in the classroom milieu is an entirely different matter which will, I suspect, depend critically upon the nature of the student clientele. The book is heavily weighted toward titrimetry, and does not provide a balanced view of analytical

chemistry. There are some noteworthy omissions. For instance, the general treatment of errors in analytical measurements is handled in a cursory .fashion (the Gaussian error curve, the qualitative significance of which is easily apprehended by sophomores, is not discussed, the term "standard deviation" never appears, and the operational distinctions between random and determinate errors are never clearly made). Likewise, separation techniques go virtually unmentioned; the term "chromatography" appears nowhere in the text. Additionally, as the authors emphasize in their preface, instrumental teehniques are not emphasized, for the logical reason that sophomore-level students generally have not had sufficient physics to grasp these methods thoroughly. In fact, Grunwald and Kirschenhaum have prepared a textbook oriented almost eaclusively around analytical solution ehemistry. My own feeling is that the suitability of this teat for adoption depends substantially upon whether the students in the course will encounter additional coursework in analytical chemistry in their undergraduate careers. If the answer t o this question is "yes", this teat should receive serious consideration, If, however, the course includes appreciable numbers of pre-medical students, engineers, or others who will encounter little, if any, additional work in analytical chemistry, this text has serious limitations. It does not attempt t o deal with the general approach to analyzing complex samples. There are some major omissions, especially chemical separation methods. Likewise, while the typical sophomore's background in physics is likely to be rudimentary, it is highly desirable to include a careful presentation of the most important instrumental methods and their limitations in any course containing a significant number of students who are not chemistry majors. One might argue that concentration upon titrimetry to the virtual exclusion of other analytical measurement procedures is undesirable even in courses populated by a high proportion of chemistry majors. With this important eamot, Grunwald and Kirschenhaum represents a refreshing departure from traditional practice, and it should greatly assist instructors of analytical chemistry to reevaluate their own approaches to presenting the more traditional aspects of quantitative analysis.
