Consider the following reaction: H_(2)O_(2) to H_(2)O + 1/2O_(2) to which I^(-) was added, A large foaming mass of bubbles was formed. The following mechanism has been proposed for this reaction. H_(2)O_(2) + I^(-) to H_(2)O + IO (slow) H_(2)O + IO^(-) to H_(2) + 1/2O_(2) + I^(-) (fast) The function of I^(-) in this reaction is to:
