Peer reviewedYip, Din-Yan – School Science Review, 1997
Presents methods commonly used for investigating enzyme activity using catalase and presents a new method for measuring catalase activity that is more reliable and accurate. Provides results that are readily reproduced and quantified. Can also be used for investigations of enzyme properties such as the effects of temperature, pH, inhibitors,…

Peer reviewedChan, 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)
