Olfactory indicators means related to sense of smell.
Those substances whose smell or odour changes in acidic or basic solution is known as olfactory indicators.
Two substnces are :
1: onion has a great smell., when basic solution of sodium hydroxide solution is added, the onion smell cannot be detected.
But an acidic solution like HCL does not destroy the smell of onion.
2: vanilla has too a characteristic smell.
If a basic solution like sodium hydroxide is added to vanilla, it can't detect it's smell.
But an acidic solution like HCL does not destroy smell of vanilla extract.
Hope this may help uh!!
