For solutions in
protic solvents, the universal
reference electrode for which, under standard conditions,
the
standard electrode potential
(
H+
/
H2) is zero at all temperatures.
The
absolute electrode potential of the hydrogen
electrode under standard conditions can be expressed in terms of
thermodynamic quantities by applying a suitable Born–Haber cycle, thus:
where
and
are the atomization and
ionization Gibbs energies of
H2,
is the real potential of
H2
in solvent S and
is the
Faraday constant.
The recommended
absolute electrode potential of the hydrogen electrode is:
