Normal pulse voltammetric waves obtained under conditions of substantial deficiency of supporting electrolyte may have heights identical to those recorded in the presence of an excess of supporting electrolyte. This is due to fast accumulation of ions in the microelectrode neighbourhood. Even such a
In electrochemical cells without transference containing an electrode of the second kind deviations between measured and anticipated cell potentials have often been observed at low common anion electrolyte concentrations, particularly when non-aqueous solvents were employed, The solubility of the sp
During our study of carbon-supported Group VIII metatloporphyrins as oxygen reduction electrocatalysts it was found that calalysts based on Rh and Ir are very active in theelectrochemical oxidation of CO, particularly when pretreated at elevated temperatures in an inert atmosphere. The active site a
The effect of solubility of sparingly soluble salts with negligible complex formation with common anions upon potentials of electrodes of the second kind is treated quantitatively. An expression for the electrode potential as a function of the actual solution composition is given and shows good agre
