This experiment uses a radioactive technique to determine the relative leaving abilities of chloride and iodide in nucleophilic substitution reactions. (DT)

Two experiments are described which illustrate preparative as well as mechanistic features of the reactions of halogens with alkanes and alkenes. (DT)

Described are several organometallic experiments for the homogeneous hydrogenation of alkenes that could be used in schools. Procedures and expected results are detailed. (RH)

Presents the author's philosophy of science which is a synthesis of the ideas of E. Mach and K. R. Popper. Describes the implications and some applications of this philosophy to the art of teaching chemistry. (GS)

The background ideas and practical implementation that led to the use of a computer terminal in a physical chemistry laboratory are described. Outlines of two of the lab experiments being used in the program are included. (DT)

Describes the use of ethyl or methyl ethanoate mixed with trichloromethane to illustrate intermolecular forces and deviations from Raoult's Law. (MLH)

Discusses the laboratory use of a titration end-point detection that relies on a temperature change rather than a color change. (MLH)

Describes an undergraduate chemistry laboratory experiment involving the production of phenol from benzene with the intermediate production of isopropylbenzene and isopropylbenzene hydroperoxide. (SL)

Describes several oscillating chemical reactions which can be used in undergraduate chemistry laboratories. In one such reaction, ferroin oscillates from red (reducing solution) to blue (oxidizing solution) for about an hour at a frequency which can readily be shown to depend on such factors as the temperature, type of solvent, and concentration…

This article describes how a gas chromatograph may be used to determine the amount of carbon dioxide in exhaled air. The experiment has been used as part of a demonstration exercise at a local science fair and proved of interest to all age groups. (Author/BB)

Describes experiments for preparing compounds containing cooper and nickel in the +3 oxidation state. (SL)

Describes experiments with and preparation of Manganese (III) for demonstrating the reactions of ions from the first transition metal series. (SL)

Describes process-based practical work used in Scottish high school examinations and evaluates this work against a standard of course objectives for practical work in general. (MLH)

Discusses methods for observing oscillations in a chemical reaction about a steady state en route to equilibrium. (MLH)

Describes an experiment involving gas-liquid chromatography of fatty acid methyl esters in petroleum ether solution. (MLH)
