Excerpt from Qualitative Analysis: A Manual for the Use of Students of Chemistry in Schools and Colleges

The method of balancing equations described on pages 8 - 11 of the Introduction was suggested to one of us (l. M. D.) in the year 1890 by Professor Gerhard Kruss of the University of Munich, and it has been used in the laboratory of Cornell University since that time.

The method of instruction used by the authors is given in page 3 of the Introduction, the preliminary study of the ele ments and groups as there outlined being then followed by the application by the student of the knowledge thus acquired to the analysis of mixtures whose composition is unknown to him. Most of these mixtures are given to the student in the solid form. If limited time or other reason makes it desirable to shorten the course as above outlined, time may be gained by omitting the first part of the course and proceeding directly to the study of such preliminary experiments as are printed in heavy type, following these with the study of the analysis of the different groups and of the detection of the more common acids, and concluding the course with the analysis of some mixtures of unknown composition.

In many operations it is desirable to use acids of six times normal strength. The formulas of acids of that strength are printed in heavy type; thus: 2804. Wherever the strength of the acid is not designated either in this manner or otherwise, dilute acid (twice normal) should be used.

Excerpt from Qualitative Analysis: A Manual for the Use of Students of Chemistry in Schools and Colleges

The purpose of the authors has been to prepare a work on qualitative analysis that shall be both exact and compendious, avoiding on the one hand the diffuseness of the larger treatises and on the other the incompleteness of the smaller manuals. Full statement has been made of the behavior of the bases toward certain reagents, but extraneous details have been omitted. Under the headings Methods of Analysis explicit directions have been given for the separation and detection of the elements, and these directions are followed in every case by a full discussion of the reasons for the different steps and of the difficulties that may arise in the course of analysis. It is hoped that this method of presentation, together with the occasional references to such articles in chemical journals as deal with debated points or new methods, may serve to arouse the interest of the student and to discourage on his part a blind and mechanical style of work that is so common in courses in qualitative analysis and is so greatly to be deplored.

The Introduction discusses in considerable detail the principles and operations involved in qualitative analysis, but it does not include the consideration of the dissociation theory.
