TRACER EXPERIMENTS WITH OZONE AS OXIDIZING AGENT IN AQUEOUS SOLUTION,
Abstract
When ozone reacts with sulfur dioxide in aqueous acid solution, as many as two ozone-oxygens appear in each product sulfate ion. Corresponding to this excess transfer (only one O being required for the oxidation), the oxygen formed is found to have undergone exchange with the solvent. In alkaline solution, transfer in excess of one O for each sulfite ion is observed and some of the sulfate oxygen is derived from the solvent despite the fact that sulfite ion is not a labile species under these conditions. Ozone induces exchange between sulfate ion and water both in alkaline and acidic solution, but the reaction is so slow as not materially to affect the results which have been described. By contrast the isotopic course of the reaction of nitrite ion with ozone in alkaline solution is simple; the nitrate ion contains two oxygens derived from the nitrite, and one derived from the ozone. Substantial ozone-oxygen appears in the manganese dioxide and thallium (III) oxide which are formed in the reaction with ozone of Mn(++)aq. and Tl(+)aq., respectively. (Author)
