Answer:
acids are very high contained h+ which is olny for acids/bases are very high contained OH ions ///
olfactory indicators are used for to find not olny it is acid or base but it changes its colour by the strength of the acid/base if it is a acid it becomes red by its strength if it is a base it becomes blue/violet by its strength (i know until here hope it may help you)
