Excerpt from Quantitative Chemical Analysis
The present edition, revised with the assistance of Dr. Lob, differs from the previous editions in that tho Introduction has been augmented by the insertion of a section devoted to theory. This was made the more necessary, since the investigations of recent years have been chiefly devoted to the explanation of the reactions in solutions, and the determination of the electrical magnitudes. The necessity of specific directions concerning electrode tension, current strength and decomposition tension has been demonstrated. The author, with the co-operation of his assistants, has experimentally determined these electrical magnitudes, not only for his own methods for the determination and separation of the metals, but also for a number of other methods, and has incorporated them in the text. Additional methods by other authors, in which directions concerning these important factors are wanting, have been omitted, in consideration of the fact that these are either uncertain or entirely impractical; mention of them has, however, been made in the references to the literature.
The book has been made more complete by the description of various measuring instruments, sources of current and apparatus; together with an explanation of simple and complete appliances for carrying out electrolytic experiments. These have been illustrated by a large number of new cuts, in the text and in the appended tables.
The publishers have spared neither pains nor expense to make these new illustrations as perfect as possible; I feel called upon to express here my full appreciation of this fact.
