Pseudo-first order rate constance for the reaction between the oxidizers peroxydisulfate, peroxide, percarbonate, and perborate ions and aqueous iodide have been measured pH 1, 4, 7, 9. Reactions were more rapid under acid conditions, and for the latter three test oxidizers, did not occur at all at pH 9. This fact has important implications for reactions to occur in seawater pH about 8.3. Observed rate constants ranged from some .00065sec peroxydisulfate at pH 1, to no reaction at high pH for some anions. Keywords Oxidizer Oxidation Iodometry Rate constances Titration.
