The electrocatalytic evolution of hydrogen on mercury electrodes by organic molecules indicates, when followed with chronopotentiometric stripping method by the ‘peak H’, that when the stripping current is changed, the mechanism of the electrode process changes. The changes become the more prominent the larger is the catalyzing organic molecule. We explain this phenomenon by dynamic interaction of the catalyzing molecule with the electrode surface.
