Succeed in your chemistry course using this lab manual's unique blend of laboratory skills and exercises that effectively illustrate concepts from the main text, CHEMISTRY FOR TODAY: GENERAL, ORGANIC, AND BIOCHEMISTRY, 8th and 9th Editions. The book's 15 general chemistry and 20 organic/biochemistry safety-scale laboratory experiments 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 macroscale quantities, which are expensive and hazardous, and more than microscale quantities, which are difficult to work with and require special equipment.

Michael R. Slabaugh
Michael R. Slabaugh is an adjunct professor at the University of South Dakota and at Weber State University, where he teaches the yearlong sequence of general chemistry, organic chemistry and biochemistry. He received his B.S. in chemistry from Purdue University and his Ph.D. in organic chemistry from Iowa State University. His interest in plant alkaloids led to a year of postdoctoral study in biochemistry at Texas A&M University. His current professional interests are chemistry education and community involvement in science activities, particularly the State Science and Engineering Fair in Utah. He also enjoys the company of family, hiking in the mountains and fishing the local stream.
