Abstract
The kinetics of oxidation of hypophosphitopentamminechromium(III) ion with periodate was investigated as a function of the temperature, ionic strength, and concentration of perchloric acid. The reaction rate decreased with increasing ionic strength and concentration of perchloric acid. The redox reaction proper involving transfer of an oxygen atom is preceded by dissociation of hydrogen from the coordinated hypophosphite. The reactivity of the latter is compared with that of the free hypophosphite.
