โฆ Synopsis
Equations of the derivative of time with respect to potential and of its peak potential and the peak half-width are derived for a reversible process in adsorption potentiometry in both stirred and unstirred solutions, when both oxidized and reduced forms #are strongly adsorbed and the Langmuir isotherm is obeyed. These equations have been verified experimentally.
