Discusses methods of measuring organic vapors, various compounds, and particulates in laboratory atmospheres, reviewing criteria for safe levels. Does not discuss other ways that toxic materials enter the body as through skin or by ingestion. (Author/JN)

Describes experiments in which acid chromate oxidation rates of four secondary alcohols are determined and related to the differences in strain relief involved in the conversion of the alcohols to their respective ketone products. All four oxidations can be completed in a 4-hour laboratory period. (Author/JN)

Discusses teaching strategies in the physical chemistry laboratory. These include taking students' personality factors into account, having students repeat the same investigation several times under partially changed conditions, presenting research problems for students to solve, and others. Indicates that approaches described may be suitable for…

Discusses the derivation of a thermodynamic relation. The relation is derived, for reactants in solution, from a treatment of the free energy of the reducing system as a function of the degree of advancement of the solution. Includes microcomputer figures/diagrams produced by programs developed to simulate this study. (JN)

Discusses storage of hazardous chemicals and provides a list of eight basic safety rules to use in developing a safe storage system. Suggestions include not storing materials alphabetically, storing nonreactive chemicals together, and not storing oxidizers and fuels together. (JN)

Describes an experiment which has helped physical chemistry students learn principles of absorption spectroscopy, the effect of solvent polarity on absorption spectra, and some micellar chemistry. Background information and experimental procedures are provided. (JN)
