Abstract
In the polarographic studies of organic substances, the occurrence of two waves the ratio of which varies with pH, was ascribed, in the early stages of polarography, to the presence of two forms in equilibrium, the equilibrium being either acid-base1,2 or tautomeric3. Nevertheless, it has been shown4 that in these cases, polarographic limiting currents do not correspond to the equilibrium concentrations (established in the bulk of the solution), but are limited rather by the rate of establishment of the equilibrium which is displaced by electrolysis at the surface of the electrode.
