Abstract
Cyclic voltammetric curves obtained at Pt electrodes for the hydrogen coupl e, H+/H-2, fit very well the Shuman theory, as corrected, for reversible el ectrode processes of other than 1:1 stoichiometry. Good agreement was obtai ned for acid concentrations in the millimolar range and for normal scan rat es, which minimize the effect of the adsorption peaks. An error in Shuman's equation for potential is corrected. Voltammograms obtained at Pt microele ctrodes fit well the theoretical simulated data.
