Excerpt from A Laboratory Manual of General Chemistry In experimental general chemistry we find but few laboratory manuals which make any pretense to a general systematic study of the elements. Whatever criticism they may have received must lie primarily in the lack of correlation of the experimental work, for the fact remains that modern chemistry demands a thorough and rigorous training in experimental general chemistry as a prerequisite for all other courses in the science. The aim of this manual is to present experimental general chemistry in a complete and detailed form and at the same time to lay great emphasis upon the correlation of all results. The study of the metals, for example, has suffered lamentably by reason of this lack of correlation and otherwise unsatisfactory treatment accorded in our manuals. Though the detailed study of the metals seems to have been left largely to the subject of qualitative analysis, there certainly need be no barrier between that subject and general chemistry. As a matter of fact, the reactions which form the basis of group separations in the former are among the most elementary of those studied in the latter. The classification, for example, of sulphides, chlorides, and carbonates finds especial attention in the study of general chemistry. The application, therefore, of these elementary principles in the simple recognition of compounds even when mixed with other compounds, but in the absence of any complicating factors, should be made a necessary training in experimental general chemistry.
