Dear student
 
 
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 olfactorytitration. Onion, clove oil and vanilla extract are examples.
We use olfactory indicators in cooking curries which are stale to eat and have disagreeable smell and change them to give agreeable

olfactory indicators" are those indicators that help to identify whether the given solution is acidic or basic by changing their smell instead of colour as other indicators do.
 
olfactory indicator" implies that this is a compound whose can smell you can detect... vanilla, clove and onion are all olfactory indicators as these do not give their distinct odour in highly alkaline(basic) medium.
