Answer:

Answer:

Option 1 and 3 are correct.

Explanation:

Buffer solution is the solution which resists the change in the magnitude of the pH when small additions of either acid or base is added.  Buffer solutions consist of weak acid and its conjugate base usually which are mixed in relatively equal and large quantities.

Hence,

Option 1. is correct because acetic acid is a weak acid and sodium acetate is the conjugate base of it which are mixed in equal concentrations.
