Riassunto

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.
