An
applied potential that is characteristic of a charge-transfer process and the experimental conditions
(such as the composition of the solvent and
supporting electrolyte and the temperature) under which it is investigated, and whose nature depends on
the technique that is employed. Some typical characteristic potentials are the
half-wave potential in
polarography, the
quarter-transition-time potential in chronopotentiometry, the
peak potential and the
half-peak potential in linear-sweep voltammetry, and the
summit potential in ac
polarography.
