Abstract
The kinetics of the reduction of perruthenate(VII) by [Fe(CN)6]4- and [W(CN)8]4- and the oxidation of ruthenate(VI) by [Mo(CN)8]3- and [Ru(CN)6]3- have been studied in aqueous alkaline solutions using stopped-flow techniques. The cross-reaction data have been treated according to the Marcus relations and yield a self-exchange rate constant of 10 ± 5 dm3 mol-1 s-1 (25.0°C, I = 1.0 mol dm-3) for the perruthenate(VII)-ruthenate(VI) couple. This rather slow self-exchange rate is discussed in terms of possible structural differences between perruthenate(VII) and ruthenate(VI) in alkaline solution.
