Iodine Clock Reaction - Effect of Peroxide

Still Images

This experiment tests the effect of different hydrogen peroxide concentrations on the rate of the iodine clock reaction. The initial concentrations and volumes of all other reactants are the same in all four vials. The greater the peroxide concentration, the less time it takes for the solution to turn blue.
