Question

why a solution of a weak base and its salt behaves as a buffer explain​

Answer 1

Answer:

weak base and salt of weak base can act as a buffer in the aqueous medium.

Explanation:

A buffer (or buffered) solution is one that resists a change in its pH when H+ or OH– ions are added or removed owing to some other reaction taking place in the same solution. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid.
