Description

Excerpt from Laboratory Manual to Accompany Chemistry: A Textbook for High Schools 1. Each exercise must be read carefully from the beginning to the end before the operation is begun. All apparatus should be prepared, and all materials should be on hand before the actual operation takes place, so that the pupils may be able to give their whole attention to observing the phenomena. 2. Every word in the sections entitled Method has been inserted for a purpose, and the pupils must not vary in the least from the directions there given. The quantities of reagents indicated must be strictly adhered to in order that the pupils may complete the experiment successfully and rapidly. 3. The questions must be studied carefully before the performance of the experiment is begun, as they frequently direct the attention to phenomena that might otherwise escape observation, and that can be observed only while the experiment is under way. The questions can be answered only after careful thought and close observation. In order to answer some of them, information not furnished by the experiment is required, and in such cases reference is generally made to a section of the text-book where the additional information can be obtained. The references to the sections in the text-book are printed in black-face type. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
