Presents a method of adopting a pH meter for overhead projection. (SL)

Presents results of a survey of New Mexico colleges and secondary schools rating expectations of graduates of secondary level chemistry courses. (SL)

Presents a detailed analysis of the thermodynamic equation dE = TdS - PdV to illustrate how chemistry teachers may present chemical potential by a route free from the terrors of partial derivatives. (MR)

A computational method is described for analyzing first-order kinetic data obtained at arbitrary time intervals. The method has uses in research and undergraduate instruction as well. (MR)

An experimental procedure is described for studying oxygen uptake by a transition metal. This procedure is designed for use with undergraduates and may be used in organic or biochemistry laboratories. Diagrams of the apparatus are included. (MR)

Two experiments are described and appropriate discussion is given to illustrate the use of substoichiometry and saturation analysis techniques with undergraduates. The first experiment is the determination of silver content in photographic film. The second is the estimation of a hormone concentration using saturation analysis and a commercially…
