The Elements Of Qualitative Analysis Classic Reprint PDF Download

Excerpt from The Elements of Qualitative Analysis Owing to a desire to bring the book up to date, especially in consequence of the researches of A. A. Noyes and his co workers, and to the further desire to incorporate in the text the subject-matter for which the students in qualitative analysis at this university are held responsible, the book has been very largely rewritten. The chief alterations made necessary by the work of A. A. Noyes were the introduction of the provisions for the proper conditions of acid concentration in the precipita tion of the Hydrogen Sulphide Group, and also in the separation of arsenic, antimony and tin; the rewriting of the entire proce dure for the analysis of the Ammonium Sulphide Group, which, owing to the above-mentioned researches, has been very greatly simplified; and the introduction of a systematic procedure for the preparation of the solution to be analyzed for the metallic elements. The procedure for the detection of acids has also been largely rewritten. The general plan of the book, however, has remained unaltered. After having performed the preliminary experiments with the metals of a group, the beginner is required to analyze a solution known to contain all the metals of the group in given quantities. Then solutions containing certain metals of the group (and sometimes of preceding groups as well) are given. Finally, solutions which may contain members of all five groups are given for analysis. Following this work, the reactions of the anions are studied, after which general mixtures of solids are given for analysis. The latter are made more and more difficult as the analyst's experience increases. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
