Abstract: The results of kinetic study of the redox reaction of the Ce(IV) ions with hypophosphites in a solution of sulfuric acid are described. On the basis of these results, the probable reaction mechanism is discussed. In particular, the dependence of the measured rate constant on concentration of hypophosphites is analyzed and the consecutive constants of complexity of the sulfate-hypophosphite cerium(IV) complexes and individual rate constants cor­responding to particular intramolecular redox steps are evaluated by the iteration method.
