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…

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)

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)

Describes the macroscopic process of the swelling of clay by adding water, and the corresponding microscopic process of water molecules entering the spacings between clay crystals. Discusses how the Bragg equation can be used together with other physical data to calculate these spacings. (MLH)

Describes experiments used to illustrate the kinetics of reversible chemical reaction. (SL)

Described is an undergraduate laboratory experiment involving synthesis of chelidonic acid and its identification in plants. The experiment is offered as an ancillary topic for biology or chemistry classes. (SL)

Describes four synthesis experiments, adapted for the general chemistry laboratory, in which compounds in unusual oxidation are prepared. The abnormal oxidation states involved in the synthesis products are: silver (II), chromium (II), lead (IV), and bromine (I). (MLH)

Describes a chemistry project in which lichens are identified by the analysis of the phenolic substances that they biosynthesize. (MLH)

Describes how a sample of iodine-131-labelled tin (IV) iodide can be used to estimate the mass of tin (IV) iodide present in a mixture with sodium chloride, by isotope dilution analysis. (MLH)

Describes an undergraduate laboratory experiment in which the position of the double bond in an alkene is determined by identifying its ozonolysis products. This experiment can also be used to introduce the technique of gas chromatography. (MLH)
