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.
