Stopped-flow spectrophotometry was used to study the oxidation of S(IV) by peroxomonosulfuric acid anion, HOOSO 3 − (=PMS), at 285 K in the pH range 0–12.5 in buffered aqueous solution under pseudo-first-order conditions ( I = 1.0 M, Na 2SO 4). The reaction of the HSO 3 − ion with PMS is subject to...
