Iodine Clock Experiment (Clock Reactions A-Level IB Chemistry)

Outlining clock reactions and how they can be used to show how the concentration of reactants affects the rate of a reaction. The iodine clock (Harcourt-Esson) experiment using hydrogen peroxide, potassium iodide and sodium thiosulfate is shown, using experimental data to find the order of reaction with respect to iodide ions.
