Book Description
Excerpt from A Laboratory Guide in Qualitative Chemical Analysis The method of instruction presented in this little book has been developed by the author in teaching the subject during the past fourteen years. The course differs materially from those usually employed, and has given satisfaction because of its tendency to obviate thoughtless and mechanical work on the part of the student - facts which may be offered as an excuse for adding another to the great number of works on qualitative analysis. The general plan of Part I, which is applied wherever it would not be too cumbersome, consists in giving directions for analyses without mentioning the results, and in requiring the student to determine for himself the results of the operations. Following this system, the student almost invariably performs his preliminary experiments with great care, because he recognizes their object and importance. This is especially the case if the student understands that, in the analysis of unknown mixtures, he will not be allowed to use any tables or abbreviated schemes of analysis. The methods of analysis given by Fresenius are chiefly used, but a number of changes have been made where experience has shown them to be advantageous on account of simplicity or accuracy. A few novelties are introduced in the way of details of processes or combinations of methods, but it may be stated that these have been thoroughly tested and may be relied upon as trustworthy. An original method, now published for the first time, is used for the detection of chlorides in the presence of bromides.

Book Description
Excerpt from Qualitative Chemical Analysis: A Laboratory Guide In this edition, the greater portion of the text has been rewritten and new material added, although the general plan of the original work has been retained. Under "Laboratory Exercises" a large number of chemical equations have been introduced for the purpose of emphasizing the reactions. The lists of questions at the close of each group of elements have been enlarged. In Part V, tables of chemical compounds have been added. Part VI is entirely new. This includes the less common elements, which are important on account of their technical use. This section will be of value to those desiring an extended course in qualitative analysis. The author trusts that this edition will prove useful as a classroom guide, and that it will offer concise and accurate information as a reference work in the field of qualitative chemical analysis. The author's acknowledgments are due to Dr. J. C. Olsen for valued criticism and to Mr. J. P. Kelly for his assistance in reading the proof.
