Kinetics and mechanism of the reduction of hydroxylamine-O-sulfonic acid by the hexaaquochromium(II) ion

The title reaction takes place with a 2:1 (Cr{sup 2+}):(HSA) stoichiometry (HSA = hydroxylamine-O-sulfonic acid) and yields CrNH{sub 3}{sup 3+}, Cr{sup 3+}, and CrSO{sub 4}{sup +} as the main products. The kinetics conform to the rate law {minus}d(HSA)/dt = {minus}d(Cr{sup 2+})/2(dt) = k{sub obs}(Cr...
