Characteristics of the dropping mercury electrode below the limiting current

Abstract

A mode.l has been developed to describe the combined effect of electro~ chemical kinetics, ohmic potential drop, and mass transfer for a metal~ deposition reaction at a dropping-mercury electrode. Current, potential, and surface concentration are expressed in terr~ of two parameters which characterize the results, For certain parameters, even in the presence of an excess of supporting electrolyte, the current density from a metal~ deposition reaction can exceed the mass~transfer limit calculated by
