Kinetics and mechanism of the oxidation of hydroxylamine by iodine
Abstract
The rate law for the iodine oxidation of hydroxylamine in acidic aqueous solution has been determined and a plausible mechanism is suggested. The reactivity of unprotonated hydroxylamine is much higher than that of the protonated form. The reaction is autoinhibitory: the rate is inversely proportional to the first and second power of the iodide concentration due to two pre-equilibria.
