Description
Six years have elapsed since the appearance of the Fourth Edition of this book. The general plan and purposes of the course therein outlined have continued to meet satisfactorily the problem of first-year college students in chemistry, yet the number of improvements and supplementary preparations and exercises that the present authors have accumulated and in part used hi pianograph form has so increased that a new edition seems to be in order. A very considerable portion of the text has been wholly rewritten, and the entire text has been subjected to a revision and rearrangement. Specific new exercises and discussions which have been introduced include such topics as the determinations of vapor density and molecular weight, the standardization of acids and the titration of acids and bases, Faraday's law, and the use of the pH scale of hydrogen-ion concentration. Several new preparations have been introduced, and a few of the old ones have been discontinued. A complete list of apparatus and chemicals required in the course has been added to the Appendix.The purpose of this, as well as of the former editions, may be indicated by a brief statement of the manner in which it is used with the large freshman class at the Massachusetts Institute of Technology. The entire year's work for both laboratory and class room is outlined in this book. Each year a list of experiments and preparations is made out and posted. All students are supposed to perform these exercises (thirty laboratory periods of three hours each in the course), and the class room exercises (sixty hours) are built around the methods and principles of this work. The lectures in chemistry (sixty hours) follow approximately the order in which the elements are taken up in the book, but no attempt is made to keep in exact step. The historical, industrial, and economic aspects of chemistry are left largely to the lectures, whereas the discussion of problems, both numerical and manipulative, is left for class room and laboratory.
