Chan, K. M. – School Science Review, 1984
Gives a detailed description of the constructon of equipment needed for redox equilibria experiments and the measurement of the electromotive force of voltaic cells. This information is provided to solve the problem of inadequate, expensive equipment required for A-level chemistry practical work. (JN)
