AQA 'AS' and 'A' level Chemistry required practicals suitable for use with a colorimeter.
Investigation of how the rate of a reaction changes with temperature:
To investigate how the rate of the
reaction of sodium thiosulfate with hydrochloric acid
changes as the temperature of the reaction is changed.
Measuring the rate of reaction by an initial rate method:
An ‘Iodine Clock’ experiment: To investigate the
reaction of iodide(V) ions with hydrogen peroxide in acidic solution
and to determine the order of the reaction with respect to iodide ions.
