Corwin's Laboratory Manual for Introductory Chemistry offers a proven format of a pre-laboratory assignment, a stepwise procedure and a post-laboratory assignment while emphasizing environmental considerations. The lab manual can be packaged with any Pearson Intro Prep Chemistry book.

The 7th Edition continues to evolve with increased sensitivity to environmental and safety concerns. Recycle icons in the margin of each procedure alert students you to recycle chemical waste, and green chemical indicators remind you to use the appropriate waste containers to dispose of chemicals.
