Dear student
Two examples of olfactory indicators are Onion and vanilla extracts. When either of the two are mixed with a solution containing an acid, the smell of the indicator does not change. Whereas, when mixed with a solution containing a base, the smell of the indicator fades away and cannot be detected.
