learning more from the open-ended Apple exercises than from the textbook prohlems. I enjoyed using Barrow's programs for lecture demonstrations, which 94% of the students thought were helpful. The graphics are well written and appropriate for the concepts being taught. The format of our lecture hall is very convenient for computer demonstrations: the Apple drives monitors located throughout the hall for good visibility. In view of the favorable student response, and their recommendation to make greater use of Barrow's programs, I will increase the proportion of Apple exercises from 1:10 to 2% in Chem 331 next year. I will also distribute appropriate sections of Barrow's Study Guide with the homework assignments. Despite the divided and negative responses by Chem 332 students.

This book presents a unique and earefully thought out approach to the equilibrium calculations underlying analytical titrations. The authors state that it is intended to he a workbook, rather than a textbook. However, there is considerahle useful discussion of principles as well as many worked out examples. The special character of the hwk lies in the close relationship of the problems to precise plots of titration curves and species distribution diagrams. Each problem provides sufficient information to deduce the coordinates (e.g., pH and fraction titrated) for one point on a curve. The emphasis on plots is valuable for the constant overview of a riven svstem. "l'he boo* begins with a sound treatment oi basic concept. iuch as cmwntration and itoichiometry calculations are related to gravimetric analysis and titrations. Succeeding chapters treat acid-base equilibria and titrations including polyprotic systems, metal-ligand complex systems, precipitation equilibria, and redox systems including galvanic cells. The discussion is brief by design but unusually comprehensive in scope. Far example, a discussion of acid-base buffer capacity is well presented including its calculus-based derivation. The treatment of metal-ligand titrations includes the complexities of metal indicator equilibrium theory. Theoretical treatments of titration error are also included. Although the reader is cautioned that "all equilibrium constants must hecorrected for ionic strength effects if meaningful answers to problems are desired," the authors have largely left this up to the user rather than repeatedly showing how this is done.
