Describes a quantitative chemistry experiment, conductometric titration, which was adapted for a blind student. Indicates other areas which can be adapted for similar experiments. (TS)

Describes simulated chemistry experiments programed into a Wang 360 programable calculator. Gives data on a sample titration simulation. (TS)

Suggests that adequate attention should be given to lattice imperfections in teaching solid state chemistry. Some concepts to be included in such a program are explained. An experiment to be performed by undergraduates on photomicrography is described in detail. (PS)

Short articles on the determination of the activation energy of the thiosulphate-acid reaction, an experiment on hydrolysis of similar metal salt solutions, the preparation and electrolytic properties of iodine monochloride and iodine trochloride, and instructions for apparatus enabling laboratory study of the thermal cracking of ethylbenzene.
