Question

when a solution is added to a cloth strip treated with onion extract in the smell of onion cannot be detected state whether the given solution contains an acid or a base

Answer 1

Answer:

Base

Explanation:

Basic solutions subdue the pungent smell of onion,

however acidic solutions have no such effect. Hence we

can say that, the cloth strip must have been treated with

a basic solution.

Answer 2

Answer:

The given solution contains base because onion extract is one of the olfactory indicators and they either change their smell or lose it when treated with an acid or base and onion loses its smell when it is treated by a base.

hope this helps
