Kinetics of cobalt(III)+ iron(II) reaction by platinum-electrode chronoamperometry in aqueous perchloric acid solution
Abstract
The rate of the CoIII+ FeII reaction in 3 mol dm–3 HClO4 is obtained by amperometry and confirms (corrected) results from stopped-flow experiments. Three current questions about the state and reactivity of CoIII are discussed and partly resolved; in particular E° for CoIII/CoII is confirmed as being 1.8–1.9 V.
