Answer:

A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH of the solution can be determined visually. Hence, a pH indicator is a chemical detector for hydronium ions or hydrogen ions in the Arrhenius model.

{\huge{\boxed{\mathcal{\pink{Answer}}}}}

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.
