Abstract
The kinetics of oxidation of the bisbipyridyl and the ethylenebisbiguanide complexes of silver(I) by the peroxydisulphate anion have been studied. The silver(II)–bipyridyl complex is formed in a reaction which is first order in both reagents, while the silver(III) complex is formed by two consecutive reactions, each being first order in both reagents. This evidence suggests that the interaction between silver and peroxydisulphate involves a one-electron process.
