Excerpt from Introduction to Inorganic Chemistry
This book, the first draft of which was written six years ago, is the outgrowth of the introductory course in chemistry which the author has given for the past fifteen years. A subject undergoing the persistent, though unconscious criticism of keen minds should gain in self-consistency and coherence as it is presented year after year. For example, an answer must be found for the common question, "Why does the chemistry of the laboratory differ from the chemistry of the text-book and the lecture to such an extent that they seem to be different sciences?" The chemistry of the laboratory is, of course, the only real chemistry, and that of the lecture must be somewhere at fault. The Student neither sees nor weighs atoms, for instance, and so the details of the laboratory experiment, which are seen and studied, become the basis of the whole treatment. The atom and the ion assume the role of merely figurative aids in the description of the facts. Gradually the conception of chemical equilibrium comes to contribute the major part of the explanation which is essential to the evolution of a system of chemistry founded upon experiment.
In the choice and arrangement of the material, several principles have served as guides:
The book is intended primarily for students beginning the study of chemistry in a college, university, or professional school. It is assumed that use of the book goes hand in hand with systematically arranged laboratory work in general chemistry. The first four chapters, for example, contain a discussion of a few typical experiments. They appeal directly to experience derived from the performance and observation of these and other similar experiments in the laboratory and in the class-room. In these chapters some of the features which are characteristic of every chemical phenomenon are sought out, put into words, and illustrated.
