The isotherm for the underpotential deposition (UPD) of mercury from solutions of mercurous or mercuric ions is the same. At the equilibrium potential of a liquid mercury electrode in either of the solutions, the surface coverage of mercury species is . However, only faradaic charge sufficient to deposit of is consumed and of appear to be adsorbed along with the UPD .
