The fifth edition of this fully accurate and well-tested lab manual contains 15 general chemistry and 20 organic/biochemistry safety-scale laboratory experiments. The experiments are designed to use small quantities of chemicals and emphasize safety and proper disposal of materials. "Safety-scale" is the authors' own term for describing the amount of chemicals each lab experiment requires--less than macro scale quantities, which are expensive and hazardous, and more than micro quantities, which are difficult to work with and require special equipment. This lab manual provides a blend of laboratory skills and exercises that illustrate concepts from the main text.
