Abstract
The oxidation of HgI by CeIV has been studied in aqueous H2SO4. A minute amount (10−6 mol dm−3) of OsVIII is sufficient to catalyse the reaction. The active catalyst, substrate and oxidant species are H2OsO5, [Hg2(SO4)HSO4]− and H3Ce(SO4)− 4, respectively. Possible mechanisms are proposed and the reaction constants involved have been determined.
