Peer reviewedThompson, Robert Q. – Journal of Chemical Education, 1988
Describes a laboratory exercise in which acid dissociation constants and molecular weights are extracted from sample data and the sample is identified. Emphasizes accurate volumetric work while bringing to practice the concepts of acid-base equilibria, activity coefficients, and thermodynamic constants. (CW)

The target of difficulty of the Educational Technology Center (ETC) Heat and Temperature Group is basic thermal physics, particularly the differentiation between heat and temperature. High school teachers often find that thermal concepts are very difficult for their students to master and attribute students' difficulties at least in part to the…
