Answer 2

Answer:

An Olfactory indicator is a substance whose smell varies depending on whether it is mixed with an acidic or basic solution. Olfactory indicators can be used in the laboratory to test whether a solution is a base or an acid, a process called olfactory titration.

Simply put, olfactory indicators are substances which have a different odour in acid and base solutions. For eg: Vanilla extract has a characteristic pleasant smell, onion and clove oil, etc.
