For the calomel half-cell, `Hg, Hg_(2)Cl_(2)|Cl^(-)(aq)` values of electrode potentials are plotted at different log `[Cl^(-)]`. Variation is represented by

Electrode potential of the half Pt(s)|Hg(l)| Hg_(2)Cl_(2)(s) | Cl^(-)(aq) can be incresed by :

Electrode potential of the half Pt(s)|Hg(l)| Hg_(2)Cl_(2)(s) | Cl^(-)(aq) can be incresed by :

Electrode potential of the half Pt(s)|Hg(l)| Hg_(2)Cl_(2)(s) | Cl^(-)(aq) can be incresed by :

The reducation potential of a Pt(s)|Cl_(2)(g)|Cl^(-)(aq.) electrode is found to be 1.42 V when the pressure olf Cl_(2) is 0.25 arm. The concentration of chloride ion in this half cell is
