Kinetics and mechanism of the oxidation of phosphite with chloramine T catalyzed by osmium(VIII) in alkaline solutions
Abstract
The osmium(VIII)-catalyzed oxidation of phosphite by chloramine T was studied by determining chloramine T (cat) iodometrically. The rate law (i) holds for [OH–]= 0.05–0.5 mol dm–3 and [HPO32–]= 0.005–0.05 mol dm3–, where K1 is defined by equation (ii); K2 and K3 are the –d[cat]/dt=
