Summary
The stoichiometry and kinetics of the oxidation of hydroxylammonium ion by the 12-tungstocobaltate(III) anion has been studied in hydrochloric acid medium. The ratio of mols of oxidant consumed per mol of hydroxylammonium ion is 1∶1 and the evolution of nitrogen is confirmed. In the 0.1–1.0 mol dm−3 [H+] region, the oxidation is acid-independent and obeys the empirical rate law: −d[oxidant]/dt=k[oxidant] [reductant] where k=(3.51±0.18)×10−4 mol−1dm3s−1 at 22.4±0.1‡C and I=2.0 mol dm−3 (NaCl). Possible reaction steps and mechanism are suggested.
