The kinetics of the reaction between copper(l) and oxygen in aqueous chloride has been studied by an amperornetric technique. The rate of oxidation by oxygen was found to exhibit a complex dependence on the concentration of copper(l) and also to be inhibited by copper(ll) ions. Experimental evidence for the formation of peroxide as an intermediate in the reduction of oxygen is presented. A mechanism is proposed that involves single electron-transfer reactions, and is different to that previously published elsewhere. The source of the difference is attributed to the limited range of experimental conditions under which the previous work was carried out.
