The kinetics of the decomposition of aqueous peroxonitric acid, O2 NOOH, have been studied as a function of pH in the range pH = 0-9. In addition to literature studies on the stability of peroxonitric acid solutions two more reactions have been measured. They are assigned to the formation and the decay of a short-lived intermediate. The composition of the intermediate is discussed. A peroxo-species containing two nitrogens in different oxidation states (+III and +V) is favoured.
The kinetics of the oxidation of S(IV) by peroxonitric acid as well as by the intermediate have been studied as a function of pH in the range pH = 0-8.2 (T = 285 K, I = 1.0 M NaC104).
