Synopses & ReviewsPublisher Comments: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. Corwin provides alerts to procedures that should be performed carefully and prelaboratory questions regarding safety; operations that present even minimal danger are omitted. He suggests environmentally friendly chemicals that do not contain lead, mercury, chromium, chloroform, or carbon tetrachloride. 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. Safety Precautions; Locker Inventory; Introduction to Chemistry; Instrumental Measurements; Density of Liquids and Solids; Freezing Points and Melting Points; Physical Properties and Chemical Properties; Atomic Fingerprints; Families of Elements; Identifying Cations in Solution; Identifying Anions in Solution; Analysis of a Penny; Determination of Avogadro's Number; Empirical Formulas of Compounds; Analysis of Alum; Decomposing Baking Soda; Precipitating Calcium Phosphate; Generating Hydrogen Gas; Generating Oxygen Gas; Molecular Models and Chemical Bonds; Analysis of Saltwater; Analysis of Vinegar; Electrical Conductivity of Aqueous Solutions; Activity Series of Metals; Organic Models and Functional Groups; Separation of Food Colors and Amino Acids. A useful reference for chemistry professionals. Synopsis: Paying particular attention to the environmental issue, the Fifth Edition of this popular chemistry lab manual retains an effective format of a prelaboratory assignment, a stepwise procedure, and a postlaboratory assignment.

A useful reference for professionals in the allied health chemistry fields. About the AuthorCHARLES H. CORWIN, educated at San Jose State University, has been perfecting his approach to teaching students chemistry for the past two decades. Through special National Science Foundation funding, he studied creative learning systems early in his career, focusing specifically on the introductory chemistry course. It is from these early seeds that Introductory Chemistry: Concepts and Connections has grown. At present, his active areas of research are web-based chemical education, conceptual and algorithmic learning models, and collaborative learning and group work. Currently, Charles Corwin is a professor of chemistry at American River College, where he was recognized with a teacher of the year award for innovative teaching in 1994. He was also the recipient of an alumni teaching award from Purdue University in 1998. Table of Contents
