Preferred Label : Donnan equilibrium;
IUPAC definition : The equilibrium characterized by an unequal distribution of diffusible ions between
two ionic solutions (one or both of the solutions may be gelled) separated by a membrane
which is impermeable to at least one of the ionic species present, e.g. because they
are too large to pass through the pores of the membrane. The membrane may be replaced
by other kinds of restraint, such as gelation, the field of gravity, etc., which prevent
some ionic components from moving from one phase to the other, but allow other components
to do so.;
