by F. Franks, Plenum Press, New York and London 1973. Vol. 2. Water in Crystalline Hydrates, Solutions of SimpIe Non-electrolytes. Vol. 3. Aqueous Solutions of Simple Electrolytes
These are the two volumes most likely to be of interest to electrochemists in a five volume set. Volume 1 is devoted to the Physics and Chemistry of Water, itself, and the remaining volumes to colloid, polyelectrolyte and more biological aspects. The treatment of non-electrolytes and electrolytes together in a single volume would have been preferable, as the editor had originally intended, but even the best conceived projects tend to outgrow the editor’s intentions. The electrochemist familiar with the style of ‘Modern Aspects of Electrochemistry’ will feel at home and find much of profit in some of the essays presented here. Outstanding in Vol. 3 is a lengthy contribution by Friedman and Krishnan on the “Thermodynamics of Ion-Hydration” presenting a novel approach to a heavily trodden path. Verrall, Lilley and Hertz provide respectively treatments of i.r., Raman, and n.m.r. relaxation, spectroscopy complementing chapters by Luck, by Blandamer and Fox and
Aqueous
by Zeidler in Vol. 2, and by Walrafen and by Glasel in to discuss Vols. 2-3 in isolaVol. 1 (it is quite impossible tion from Vol. 1). The editor, himself contributes an interesting review on the “Solvent Properties of Water”, which is elfeectively an introduction to both volumes 2 and 3, and two chapters on hydrates appear rather as an interpolation. lt is always possible to query the aims and execution of a project such as this, to have doubts about its comprehensiveness, the balance etc. Nevertheless, it is certain that much of value will be found for some years to come in having these volumes available on a library shelf. It is even to be hoped that those electrochemists who accept the patronizing description, in a recent two-volume text, of solution studies bemg “the supportive aspect of electrochemistry”, will appreciate the importance of the material presented.
