Reviews legislation and controls in effect, and needed, to reduce the hazards of violent reactions in the uncontrolled mixing of incompatible chemicals. (SL)

Discusses application of Schoniger's method of quantitative organic elemental analysis in teaching of qualitative analysis of the halogens, nitrogen, sulphur, and phosphorus. Indicates that the oxygen flask method is safe and suitable for both high school and college courses because of simple apparatus requirements. (CC)

Discusses the code of the Royal Institute of Chemistry (RIC) in Great Britain concerning laboratory safety; includes sections on hazardous chemicals and techniques, and legal responsibilities. (MLH)

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

A discussion concerning the choice of solvents for a chemical reaction is followed by an examination of the advantages of using liquid ammonia, oxide solvents, and molten salts as alternatives to water as a solvent. (DT)

Discusses means of disseminating information about hazardous laboratory materials and situations; includes student-student contact, student-teacher contact, textbooks, research papers, and government services. (MLH)

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)

Discusses the operation of the Health and Safety at Work etc. Act 1974 in relation to British universities. (MLH)

Discusses types of laboratory waste materials and methods for their safe disposal. (MLH)

A new scale is suggested, with the objective of simplifying relationships between the various scales and units used in spectroscopy. Although there are certain drawbacks to such a scale, it is hoped that the suggestion will stimulate discussion on the relevance of the many scales and units that are used. (Author/BB)

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)

Describes some of the problems likely to be encountered by British science teachers and school science departments in the implementation of laboratory standards under the Health and Safety at Work etc. Act 1974. (MLH)
