Direct linkCorcoran, K. Blake; Rood, Brian E.; Trogden, Bridget G. – Journal of Chemical Education, 2011
This project involved developing a method to remediate large quantities of aqueous waste from a general chemistry laboratory experiment. Aqueous Ni(II) waste from a general chemistry laboratory experiment was converted into solid nickel hydroxide hydrate with a substantial decrease in waste volume. The remediation method was developed for a…

Waghorne, W. Earle; Rous, Andrew J. – Journal of Chemical Education, 2009
Students determine the relative atomic masses of calcium, magnesium, and aluminum by reaction with hydrochloric acid and measurement of the volume of hydrogen gas liberated. The experiment demonstrates stoichiometry and illustrates clearly that mass of the reagent is not the determinant of the amounts in chemical reactions. The experiment is…

Bullard, Lisa G.; Felder, Richard M. – Chemical Engineering Education, 2007
This two-part series describes the structure of the stoichiometry course at North Carolina State University. The course had a variety of learning objectives, and several nontraditional pedagogies were used in the course delivery. This first paper outlines the course structure and policies, the preparation given to the teaching assistants who…
