Abstract

A one-semester laboratory has been developed in which principles of general chemistry (aqueous acid–base equilibria, kinetics, thermodynamics, chromatographic separations, spectroscopy) are presented in the context of environmental aquatic chemistry. Some of the experiments in the sequence are modified slightly from standard experiments, but new experiments have been added to teach kinetics and separations in the context of halocarbon removal from water. A final capstone project on wastewater treatment reinforces and integrates concepts taught in the earlier experiments. Survey data confirm that the contextual format is stimulating for students because of added relevance to real-world environmental issues.
