Iodine Clock Reaction - Effect of Iodide

Still Images

This experiment tests the effect of different iodide ion 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 iodide concentration, the shorter the reaction time.
