A Laboratory Manual Of The Chemistry Of The Metals PDF Download

Excerpt from A Laboratory Manual of General Chemistry This the fourth edition of the author's Experiments in General Chemistry is printed, as its predecessors have been, primarily for the use of students in general chemistry in Grinnell College. This fact may explain certain departures from custom in the preparation of such books, such as suggestions to teachers and detailed descriptions of apparatus and its manipulation. As a matter of fact apparatus at all complicated is not only shown by cuts, but it is set up on the lecture table and many experiments for any period are there carried through before the students enter the laboratory. Some apparatus is even set up in the laboratory and left there for inspection during the laboratory period. Not satisfied to use the same set of even his own experiments year after year and wishing to provide new laboratory work for classes of students who have taken chemistry in the high school, the writer has provided for more laboratory work than can be done in a three- or four-hour course of one year. In this book an attempt is made to connect rationally general chemistry and qualitative analysis. Students who complete a first year course in chemistry should have some knowledge of qualitative analysis, but it should not be permitted to take the place of general chemistry in the second half year, which is usually devoted to study of the metals. Qualitative analysis ought to be a development from the general chemistry to which it gives point, and its introduction as an outgrowth of the general chemistry greatly stimulates the student's interest in both subjects. In this book tests for acids and other compounds are given in the study of the non-metals, and a system for the detection of acids is given after the study of the non-metals has been completed. In the study of the metals emphasis is placed on properties that are of analytical significance, though other facts are not neglected. After each group of metals has been studied their separation is taken up, and the work is extended as rapidly as the student's experience justifies it, to the detection of both metals and acid radicals in "unknowns." The scheme of qualitative analysis as outlined is not supposed to be complete but is meant to serve as an introduction to the subject and a preparation to the more rigorous course in qualitative analysis the following year.
