Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Notes on Electrochemistry The principal aim kept in view in the preparation of these notes has been the giving of a clear and concise presentation of the general principles which underlie electrochemical science. Endeavor has been made to meet the needs of students entering upon the study of electrochemistry and of chemists interested in the application of electrical energy to chemical problems. The literature of electrochemistry counts as its own a number of standard works which treat in detail the theories of the science, the methods of electrochemical analysis, and the applications of electrochemistry. Differing from these, the present notes aim merely to offer a general survey of the subject, to serve as an introduction to its study and to aid in the securing of a proper understanding and appreciation of the work along individual lines. In the chapter on electrotechnology, special endeavor has been made to secure the most recent and reliable data and full advantage has been taken of the information given in leading technical journals and in the excellent monographs of Foerster: Elektrochemie Wasseriger Losungen, and of Wright: Electric Furnaces and their Industrial Applications. It must however not be forgotten that exact data of technical operations are often very difficult to procure, and therefore the figures given, while well indicating the general conditions obtaining, cannot in all cases claim to be actual working formulae.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Experimental Electrochemistry It has been the aim of the author to produce a book that will prove useful in both the lecture room and in the laboratory. Although a work upon the subject of electrochemistry must presuppose a working knowledge of chemistry and electricity, it has been the object of the writer to introduce the subject as clearly as possible, dealing with chemistry and electricity without assuming too much on the part of the student. The book is so written that it may be read through as a history by the student, presenting theory and practice together, with the introduction of an ample number of experiments to supply experimental evidence for the theories advanced. In the later and more practical part of the book, exercises in preparing electrolytic compounds and in isolating metals are introduced. It has also been the aim of the writer to introduce new material with suggestions for additional experiments with the hope that the work will not be unwelcome to those already well informed in the subject. Electrochemistry is at best a subject for the advanced student, and in order to carry out the experimental work with profit, as given here, he must have pursued beforehand laboratory courses in both chemistry and physics. If the more mature and experienced student profits by a study of the book, or the instructor obtains assistance in teaching or suggestions for new work, the object in writing the book will be attained.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Standard Table of Electrochemical Equivalents and Their Derivatives: With Explanatory d104 on Electrochemical Calculations, Solutions of Typical Practical Examples and Introductory Notes on Electrochemistry The methods of making electrochemical calculations involving these equivalents are described by means of a number of typical practical examples accompanied by explanatory notes. A brief description of some of the elementary principles of chemistry involved in such calculations, has been added. Some of the conceptions and simplified methods of calculation described in the text may differ from those more generally taught or found in textbooks; they are offered here merely as suggestions which lead to the same result as the older and more complicated ones; the latter are also described as alternatives to be used by those who prefer them. The rapid developments of recent years in the physical conceptions of electrochemical phenomena made it desirable to include an introductory description of them in a section on the Electronic Theory. This, and a section on Electrolysis which includes a brief explanation of the dissociation theory, have been prepared by the other author, Frederick H. Getman. The authors acknowledge their indebtedness to Dr. J. W. Richards for revising and bringing up to date his table of the valences which the elements have in their more usual combinations. Also to the Bureau of Standards for most of the fundamental constants and for valuable advice and assistance.

Book excerpt: Excerpt from The Elements of Electro-Chemistry With the exception of a few alterations, either suggested or accepted by Professor Le Blanc, the present work is as nearly as practicable a literal translation. The rapid advance of the subject within the past few years has rendered treatises which adequately present it scarce, therefore I hope to have satisfied a want, and to have increased the facility of study for the English reader in this field. It is with pleasure that I express here my great indebtedness to Mr. J. A. Craw of Glasgow, Scotland, for the aid he kindly gave me in the translation, and to Professor A. A. Noyes of the Massachusetts Institute of Technology, Boston, U.S.A., for correcting the proofs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Text-Book of Electrochemistry The basis of this book is a series of lectures delivered by me at the University of Stockholm in the autumn of 1897. The English translation has been made from the German edition. In the German translation, made by Dr. H. Euler, many improvements and additions to the original Swedish edition were introduced with reference to the literature up till 1901. Only few alterations have been made in the present edition, and these refer mainly to typographical errors. By the list of literature-references collected by Dr. McCrae considerable value has been added to the book.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electro-Chemistry With Positive Results 1. Are the two electricities material elements? The late Dr. Turner, in his Elements of Chemistry, states that the "effects of electricity are so similar to those of a mechanical agent - it appears so distinctly to emanate from substances which contain it in excess, and rends asunder all obstacles in its course so exactly like a body in rapid motion, that the impression of its existence as a distinct material substance, sui generis, forces itself irresistibly on the mind. All nations, accordingly, have spontaneously concurred in regarding electricity as a material principle; and scientific men give a preference to the same view."

Book excerpt: Excerpt from Electro-Chemistry: Inorganic No separate treatise on electro-chemistry exists in the English language. The facts relating to the subject lie scattered in a great number oi_ books and periodicals. Perceiving the utility of such a treatise, I have collected the numerous truths yet discovered in the subject and arranged them in consecutive order in the following pages. The treatise is not, however, merely a systematic and orderly collection of facts, but contains also brief descriptions of the known laws and general truths which underlie them.

Book excerpt: Excerpt from Practical Methods of Electro-Chemistry The reasons for writing this book - the first of its kind published in this country - have been twofold. In the first place, I have felt the want of such a book for my own students. In the second place, the work was undertaken in the hope that interest in electro-chemistry might be stimulated. The book has been some years in preparation, owing to the fact that I did not wish to include any experimental work which had not been personally tested or supervised. With a few exceptions - in the separation of the metals - all the experimental work has been carried out in the laboratories of the Borough Polytechnic Institute. All the possible methods of analysis have not been given, but those included have been found to give the best results. Many of the analytical methods are superior, in the ease with which they may be carried out and in accuracy, to ordinary chemical methods; others still leave a good deal to be desired.
