Investigating the affect of concentration on the rate of reaction
Introduction:
This investigates how the rate of a chemical reaction depends on the concentration of reactants in the solution. This will be investigated with the following experiment in which dilute hydrochloric acid and sodium thiosulphate solutions are mixed. This forms insoluble sulphur and the mixture gradually becomes cloudy.
If the concentration of the sodium thiosulphate concentration is varied, the rate of production of sulphur can be measured by recording the time taken for the reaction mixture to go cloudy.
