calomel half cell

Chemistry

A type of half cell in which the electrode is mercury coated with calomel (HgCl) and the electrolyte is a solution of potassium chloride and saturated calomel. The standard electrode potential is –0.2415 volt (25°C). In the calomel half cell the reactions are
$\begin{array}{l} HgCl (s) ⇌ {Hg}^{+} {(aq) + Cl}^{-} (aq) \\ {Hg}^{+} (aq) + e ⇌ Hg (s) \end{array}$
The overall reaction is
${HgCl (s) + e ⇌ Hg (s) + Cl}^{-} (aq)$
This is equivalent to a Cl₂(g)|Cl⁻(aq) half cell.
