Answer 2

The odor of clove oil vanishes in NaOH and remains unchanged in HCl.

Justification for the above Answer:

• Substance or things like clove oil act as an olfactory indicator.
• They are natural indicators for acid and bases.
• They change their odor in bases while remaining unchanged in acids indicating the pH of the substance.
• These olfactory indicators are called so because the change in their odor on mixing or reacting with an acid or a base helps in finding out the pH.
• So, their odor acts as a natural indicator, which can be easily found.
• Other such olfactory indicators are onions and vanilla or vanilla essence.
