| Abstract: | The kinetics of oxidation of iodide ion by hydrogen peroxide in aqueous phosphoric acid has been studied by means of the Pseudo-Order and initial-rates methods. Under controlled the experiment conditions, it shows that the overall reaction kinetics follows the shows that of zero order reaction in mixed phospho first order reaction in phosphoric acid aqueous solution; and it ric and sulfuric acid solution,. The sulfuric acid catalyst in the oxidation mechanism analyzed in this paper. The study also found that the hydrogen ion concentration had to play a intricacy role in this reaction. |
