This is the latest version of Charles H. Corwin’s best selling lab manual, which has been used by over 250,000 students. This fourth edition retains the highly effective format of a prelaboratory assignment, a stepwise procedure, and a postlaboratory assignment. These experiments have been used successfully with students enrolled in Introductory Chemistry, Preparatory Chemistry, and Allied Health Chemistry.
