This is the latest version of Charles H. Corwin’s best-selling, widely used lab manual. The Fourth Edition retains the highly effective format of a pre-laboratory assignment, a stepwise procedure, and a post-laboratory assignment.

Line art illustrations demonstrate techniques for reading a metric ruler, graduated cylinder, thermometer, and buret; and instructions for using a laboratory burner, platform balance, beam balance, electronic balance, and volumetric pipet
