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)

Described are some new uses and procedures of titration procedures. Topics included are titration in non-aqueous solvents, thermometric titration and catalytic methods for end-point detection, titration finish in organic elemental analysis, and sub-micro analysis and automatic titration procedures. (CS)

Described is a conductiometric method for following the course of diffusion of aquated ions through a cellulose membrane. Several experiments using the method are described. (Author/SA)

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)

Describes a method for testing the chlorine content of water. (SL)

Describes a student project in analytical chemistry using sheet silicates. Provides specific information regarding the use of phlogopite in an experiment to analyze samples for silicon, aluminum, magnesium, iron, potassium, and fluoride. (CS)

Describes a study designed to explore systematically the practical advantages and problems of using videotapes in the undergraduate chemistry laboratory. (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)

This article looks at the problems of revision of laboratory courses. While revision of the syllabus of experiments is expensive, it is necessary to keep it up to date. The nature, causes, and rates of change in practical courses are discussed. (BB)

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

Discusses an experiment which illustrates the non-mixing properties of water at normal temperature with oil because of water's strong, open-ended hydrogen bonding interactions. Examples of the mixing properties between non-interacting substances and the near-complete mixing between water and solvents with limited H-bonding capacity are also given.…

Describes a simple method for establishing the end point in a volumetric analysis that will save time, and reduce both the titration error and the required amount of reagents. (GA)
