The ionic form of an
ion exchanger in which the
counter-ions are neither hydrogen nor hydroxide ions. When only one
valence is possible for the counter-ion, or its exact form or charge is not known, the symbol
or the name of the counter-ion without charge is used, e.g. sodium-form or Na-form,
tetramethylammonium-form, orthophosphate-form. When one of two or more possible forms
is exclusively present, the
oxidation state may be indicated by a Roman numeral, e.g.
FeII
form,
FeIII
form.
