PREFACE

[ocr errors]

It is no longer necessary to emphasize the importance of laboratory work as a part of the course in elementary chemistry, since it is universally admitted that laboratory experience is essential for a thorough comprehension of the subject. It is none the less true, however, that laboratory work is of little value unless carefully directed by an experienced teacher toward some definite end. It is in the hope of aiding such a teacher that this exercise book has been prepared. The exercises are arranged to accompany McPherson and Henderson's * First Course in Chemistry."

While the experiments described may be performed with simple apparatus and inexpensive materials, nevertheless it is believed that they will serve to give the student a good insight into the elementary principles of chemistry as well as into many of the applications of the science.

Detailed information as to the apparatus and materials required for performing the experiments will be found in the Appendix. Ohio STATE UNIVERSITY
