Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A solution that resists change in pH value upon addition of a small amount of strong acid or base (less than 1 %) or when the solution is diluted is called buffer solution.Simple buffer solution: A salt of a weak acid and weak base in water e.g. CH3COONH4 AgCN.Acidic buffer solution: An acidic buffer solution consists of a solution of a weak acid and its salt with a strong base. The best-known example is a mixture of a solution of acetic acid and its salt with a strong base (CH3COONa).
