IN QUALITATIVE CHEMISTRY. BY ALBERT B. PRESCOTT, FELLOW OF THE CHEMICAL SOCIETY OF LONDON; MEMBER OF THE AMERICAN CHEMICAL AUTHOR OF "OUTLINES OF PROXIMATE ORGANIC ANALYSIS,' "CHEMICAL EXAMINATION CHEMICAL ANALYSIS." SECOND EDITION, REVISED. NEW YORK: D. VAN NOSTRAND, PUBLISHER, 1880. 08/05/05 Clift PREFACE. THIS little manual has been prepared for certain classes who take a short course in qualitative chemical work, to attain some practical acquaintance with the materials of every-day life, rather than to qualify as analysts. The scope of the work includes a more definite study of bases and acids than is taught in ordinary courses of Experimental Chemistry, and a broader study of chemical characteristics than is provided in the common rudimentary. Qualitative Analysis. When a student, with but a few months to devote to chemical laboratory work, should gain, with a little of the training of experimental science, as much insight into chemical action as he can, it is not well that his attention should be all the time directed to a set of chemical peculiarities, prominent only because of their technical use in analysis. The schemes of qualitative analysis furnish admirable avenues by which to reach the 5 |
