摘要：

The kinetics of the silver(I) ion catalysed reduction of peroxodisulphate by 12-tungstocobaltate(II) anion in aqueous HClO4 has been studied. Although the reaction in the range [H+] = 0.1-1.0 M was acid-independent, it was first-order each in Ag(I), the oxidant and the reductant. We propose that reaction proceeds by univalent changes with the production of free radical intermediates. The reduction is rationalised in terms of the outer-sphere mechanism.
