The oxidation of sodium dithionite with molecular oxygen in alkaline solutions takes place in two steps: in the first, dithionite oxidizes to sulphite and sulphate, $20 2-+O2+2OH--\*SO ] +SO 2-+H:O which occurs in the fast reaction regime; within this step the oxygen concentration in the bulk liquid
