Answer 2

Among the following, the groundnut is not an olfactory indicator. (Option c)

• The substances whose smells vary when mixed with an acid or a base are called olfactory indicators.
• Such substances are used in tests to identify acids and bases.
• The smell of groundnut does not undergo any change in presence of an acid or base.
• Therefore, it is not an olfactory indicator.
• In acid, the smell of onion and vanilla remains the same whereas in base it vanishes.
• The smell of clove remains undetectable in the presence of a base.
