Answer:

Olfactory (means: smell/odour)

Adding olfacory indicator to an acid or base varies its odour respectively with acid and base. It is used in laboratories to test if a given solution is acid or base.

Onion(paste or juice) loses its odour when it is mixed with a base (no change with an acid).
