This extensively class-tested and fully accurate lab manual contains 15 general chemistry and 18 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 authors' main book, Chemistry for Today: General, Organic, and Biochemistry, Fourth Edition.
