General Chemistry Virtual Textbook

This project began in the late 1980's as a means to supplement (or in some cases to largely replace ) the conventional textbook treatments of various topics in courses in General Chemistry and Environmental Chemistry. The motivation was in most cases to provide alternatives to what seem to be the rather shallow standardized treatments of certain topics presented in many commercial textbooks. The site contains reference text chapters, tutorials, advanced stuff, information for teachers, and more. By Stephen Lower at Simon Fraser University.
