Sinopsis

Excerpt from The Theory and Practice of Electrolytic Methods of Analysis

Since this date the employment of electrolysis both for analytical and technical purposes has extended greatly. While the most important facts - cg. The more or less good or rapid deposition of metals from different solutions, the variations in the current required, the separation of different elements or groups of elements from the same solution according to the current intensity or voltage, the influence of temperature, &c. - were long known, there was lacking, until a few years ago, a theory of electrolysis which explained clearly these phenomena.

Similarly 'there was no theory by means of which it was possible to explain clearly the changes in the energy creating couple. It is true that at the commencement of this century a violent strife arose between the supporters of the contact theory and the supporters of the chemical theory' of the origin of the energy in the voltaic cell. This strife continued into the third quarter of the century without the supporters of either the one theory or the other being enabled to give a clear explanation of the facts. Such an explanation has only become possible within the last few years, by aid of the theory of osmotic pressure, or osmosis.'

Excerpt from The Theory and Practice of Electrolytic Methods of Analysis

In the preparation of the English translation of Dr. Neumann's work on Electrolytic Methods of Analysis a comparatively small number of alterations or corrections have been found necessary; and the Author's consent has been in every case obtained for the few that have been made.

The portion of the original work dealing with primary and secondary batteries, the dynamo, and the thermo-pile has been omitted. The electro-chemical equivalents have been recalculated upon the most reliable figures for the atomic weights of the elements. The Translator has added a few notes to the original text where such notes were considered to be of utility. These notes are in every case included in square brackets, in order to distinguish them from the original text. The translation is provided with a fairly complete subject index, and a name index, which it is believed will increase the value of the book to those engaged in original research in this branch of chemistry.

With regard to the question of current supply, it may be pointed out that city and town laboratories can obtain the current required from the supply mains of the electric-lighting companies.

The installation of small transformers for reducing the current voltage to five volts, and where necessary for converting alternating currents into direct ones, is a comparatively simple matter. When continuous work is contemplated, the addition of one or two storage batteries would be requisite.
