In chronopotentiometry and related techniques, the time that elapses between the instant
at which current is applied and the instant at which the concentration of an electroactive substance
B at the electrode-solution interface
becomes indistinguishable from zero. In experimental practice the latter time is
often taken to be the instant at which the rate of variation of the potential of the
attains a maximum value.
