Excerpt from Guide to Preparation Work Chemistry Inorganic Chemistry: For Students of Chemistry and Pharmacy This little book is intended to serve as a first guide to students of chemistry and pharmacy in inorganic preparation work; it assumes that by practical work the student has already acquired a good knowledge of analytical chemistry. The rational preparation of chemical compounds must always rest upon the stoichiometric proportions of the reacting substances. The course of the reaction is given briefly under each prepara tion and then a definite exercise is assigned. The quantities of all the materials used are to be determined and weighed by the student himself. Where on practical grounds, or for other reason, a departure from the stoichiometric quantities seems to be demanded, attention is called to it and the reason sought. Hence the student cannot avoid a careful quantitative study of those chemical processes which he carries out. The amount of substance which can be Obtained, or the ratio in which this stands to the theoretical, is given, for comparison with the results obtained by the student. It is here assumed that the process is carried out to completion. Wherever it has seemed necessary, attention has been called to the indications by which the end of the Operation may be recognized, and also to the various phenomena during the reaction, which serve as a guide for its proper course.
