Overview

This comprehensive collection of laboratory experiments offers an exciting, hands-on introduction to the fascinating world of chemistry. The experiments are designed to provide three hours of lab work; each follows a successful format with highly effective prelaboratory and postlaboratory assignments. Presents a wide range of experiments that demonstrate such concepts as the metric system, the density of liquids and solids, emission spectra and electron energy levels, percent composition and empirical formula, writing chemical equations, generating hydrogen gas, building molecular models, analyzing salt water, conductivity testing, and more. Each experiment includes objectives, a discussion of the experiment with example exercises, a list of the equipment and chemicals, a stepwise procedure guide, a prelaboratory assignment, a data table to record observations and measurements, and a postlaboratory assignment. Stresses safety and lists precautions throughout. Appendices include instructions for basic laboratory techniques plus a glossary of key terms. Now revises procedures to reduce or completely eliminate chemicals that are environmentally sensitive, such as lead, mercury, or chromium. Also reduces amounts of organic solvents, and eliminates chloroform and carbon tetrachloride.
