Laboratory Manual for Principles of General Chemistry

A two-term manual for General Chemistry

This supplementary manual focuses on chemical principles and techniques. The Laboratory Manual for Principles of General Chemistry, tenth edition, provides a broad scope of experiments coupled with a clear layout for ease of use. The manual delivers material for two or three course terms. It also assists chemistry students in knowing how to time various techniques in the lab environment. The companion manual is organized into topic sections, such as Chemical and Physical Properties; Atomic and Molecular Structure; Gases; and Solutions.
