							An Olfactory indicator is defined as a substance whose smell varies when it is mixed with an acidic or basic solution.Such substances can be used in the laboratory to test whether a solution is a base or an acid, and this process is called olfactory titration. All onion,clove oil and vanilla extract are examples.
An olfactory indicator works on the principle that when an acid or base is added to it,then different odour can be detected in bases whereas odour remains same in acids.Certain substances changes odour in acidic or basic medium.
1.Onion:- Paste or juice of onion loses its smell when added with base.It does not change its smell with acid.
2.Vanilla:- The smell of vanilla vanishes with base,but it’s smell does not vanishes with an acid.
3.Clove oil- In bases its characteristis smell cannot be detected.
Dear student kindly ask the second part of your question clearly so that you can get an satisfactory answer.

Olfactory indicators:  "sense of smell"
Those substances whose smell or odour changes in acidic or basic solutions
are called olfactory indicators.
Eg: Onion extract, vanilla extract, clove oil
Onion has a characteristic pungent smell
Onion extract + base ➡️onion smell cannot be detected
Onion extract + acid ➡️does not destroy the smell of the onion
 
Vanilla extract has a sweet smell 
Vanilla extract + base ➡️ cannot detect the smell of vanilla extract
Vanilla extract + acid ➡️ can detect the smell of vanilla extract
 
Clove oil has a sweet-spicy, hot smell with fruity top notes
Clove oil + base ➡️smell of clove oil cannot be detected
Clove oil + acid ➡️smell of clove oil can be detected
