Kinetics of the SCN−/(SCN)<sub>2</sub> couple on platinum in acetonitrile
The electrode kinetics of the SCN−/(SCN)<sub>2</sub> system has been studied on platinum in the temperature range from −12 to −3°C at different ammonium thiocyanate concentrations in acetonitrile in the presence of 0·1 M [(C<sub>2</sub>H<sub>5</sub>)<sub>4&l...

| Sumario: | The electrode kinetics of the SCN−/(SCN)<sub>2</sub> system has been studied on platinum in the temperature range from −12 to −3°C at different ammonium thiocyanate concentrations in acetonitrile in the presence of 0·1 M [(C<sub>2</sub>H<sub>5</sub>)<sub>4</sub>N]ClO<sub>2</sub>. Quasi-steady E/I curves with a Pt rotating disk electrode and E/I curves at different linear potential-sweep rates were recorded under different experimental conditions. Both reactions of the pseudohalogen electrode are rather slow processes, the kinetics of which can be explained with the same mechanistic formalism postulated for the halogen electrodes in acetonitrile. |
