Defined for species B in phase β as
where
is the
electrochemical potential of species B in phase
β,
is the
charge number of species B,
is the
Faraday constant, and
is the
outer electric potential of phase β.
Since
is zero when the charge on the phase β is zero,
the real potential may be regarded as the value of the
electrochemical potential of the uncharged phase.
