Lehrhuch der Elektrochemie (Textbook of Electrochemistry).
By G. Kortiim. Verlag Chemie GmbH, WeinheimIBergstr. 1966. 4th Edit., xvi, 592 pp., illustrations and 72 tables,
D M 52.-.
Originally written for science students in their later semesters,
this book has acquired a very much wider circle of readers
owing t o the increasing importance of electrochemistry for
many areas such as biochemistry, analysis, chemical kinetics, industrial processes, and new methods of generating
electricity.
Basically, the book is devoted to the fundamental aspects.
Only occasionally are indications of industrial use to be
found in the text. The presentation of the principles covers
much material. Thus the first 40 pages are reserved for the
fundamental laws, and 45 pages are devoted to chemical
thermodynamics. In the preliminary chapter o n the preparation of pure substances the band model for the solid state is
taken up anew, thereby laying the ground for the later
treatment of electrode kinetics at semiconductor electrodes.
A third of the total number of pages is devoted solely to the
theory of electrolytes. I t contains a new section on concentrated solutions and molten salts (7 pages; the most
recent papers cited there were published in 1962).
The phase boundary electrode/electrolyte occupies the main
part of the book (five chapters). Analytical uses are here
treated at reasonable length. The accounts of studies of the
structure of the electrochemical double layer and of the
types of polarization have been thoroughly revised. Numerous references to original papers make for easier access to the
specialist literature in these fields.
The last of the 15 chapters has the title “Uses of electrochemical processes”. Here are t o be found very condensed
but clear treatments of galvanic elements, of analysis, of the
problems of electrodeposition, and of corrosion. Industrial
electrochemical processes are not described, a fact that need
not be deplored in this case, for a n increased consideration
of uses and industry in this book, which is directed to
fundamental theories, would have destroyed the remarkable
flexibility of the presentation and exceeded the limits of the
treatment.
A chapter on photopotentials and electroluminescence in
electrochemical systems could, however, have rounded off
the picture of modern electrochemistry and should indeed
find a place in this monograph.
I t is not hard to prophecy that the fourth edition will confirm
the view that G . Kortiim’s book is a standard work on
electrochemistry, and is recognized as such beyond the
boundaries of Germany.

Physikalisch-chernisches Rechnen in Wissenschaft und Technik (Physicochemical Calculation in Science and Industry).
By H . Fromherz. Verlag Chemie GmbH., WeinheimIBergstr. 1966. 3rd Edit., xvi, 341 pp., 43 illustrations, D M 35.-.
On the assumption that the fundamental physicochemical
laws can be learnt and mastered only by using them for
relevant numerical examples, the author has collected 210
problems that are taken from actual practice or are met
with daily by the physical chemist in his industrial work or
in purely scientific work in the laboratory. I n general, the
present edition does not range beyond the limits of the second
edition [*I, but a number of formal details have been modified t o meet recent international agreements.
Each of the 14 chapters is introduced by a preliminary statement of the important laws and the corresponding dimensions; but the main emphasis is always placed on setting and
solving special problems. These exercises deal with problems
of distillation technique, as well as others such as arise in

connection with rocket propulsion, operation of a nuclear
reactor, or medico-physiological work. Approximations are
often used in solving the problems, since without approximations it is often impossible to make progress in practice.
For example, the degree of dissociation is occasionally
treated as identical with the conductivity coefficent, although
these two concepts have somewhat different meanings; yet,
in practice, treating the two numerical values as if they were
equal often gives a better quantitative solution t o an equilibrium problem than is obtained by the usual neglect or
idealization of the degree of dissociation.
This book can certainly be recommended, not only to the
beginner, but also to the expert, for it contains many hints
o n how to handle special problems more quickly.

Landolt-Bornstein, Zahlenwerte und Funktionen aus Naturwissenschaften und Technik (Landolt-Bornstein, Numerical
Values and Functions from Science and Technology).
Edited by K.-H. Hellwege. Gruppe 11: Atom- und Molekularphysik. Band 11. Magnetische Eigenschaften der
Koordinations- and metallorganischen Verbindungen der
Ubergangselemente (Group I1 : Atomic and Molecular
Physics. Vol. 11: Magnetic Properties of Coordination and
Organometallic Compounds of the Transition Elements).
By E . Konig. Springer Verlag, Berlin-Heidelberg-NewYork
1966. xii, 578 pp., D M 232.-.
The present volume fully justifies the concept behind the
“New Series” of Landolt-Bornstein, according to which a
loosely connected series of rather small volumes on special
areas is separated from the rigid arrangement into a few
volumes covering wide fields. Research o n magnetic properties, which has developed so rapidly, would have been very
difficult t o include clearly within the framework of the “Old
Series”. Specialized information o n the magnetic properties
of coordination and organometallic compounds of transition
elements is collected in the volume under review.
The first part contains theresults of measurements of magnetic
susceptibility together with the temperature of measurement,
the data being arranged according to the transition element
concerned. The methods of determination and, for paramagnetic substances, the resulting magnetic moments and
0 values are also given. The arrangement thus corresponds
with the established form of the Fuex and Gorter publication
of 1957; the arrangement of literature references also
corresponds to theirs. The references extend to 1965 but are
not complete for the end of that year.
The tables are preceded by a brief introduction in which the
fundamental equations for determination of magnetic
moments from susceptibility values are given, together with
diamagnetic corrections and also the calculation of moments
with consideration given to the influence of ligand fields and
the orbital momentum components. Ferro- and antiferromagnetic interaction are also briefly mentioned but ferrimagnetic interaction i s not.
The most important and fundamental facts are skilfully
extracted. Moreover, a comprehensive review of the literature
makes it possible for the reader to obtain further information
from more detailed works (for which purpose Figgis and
Lewis’ reviews seem particularly suitable). The tabular
section (379 pages), which is supplemented by graphical
presentation of magnetic measurements (29 pages), contains
a few misprints (e.g. the reference for NbF4 is to be found
under A 65 Gi, not under 65 Gi), but these should not escape
the critical user.
