1.	Assertion (A): A solution containing a mixture of acetic acid and sodium acetate maintains a constant value of pH on addition of small amounts of acid or alkali.Reason (R) : A solution containing a mixture of acetic acid and sodium acetate acts as a buffer solution around pH 4.75.
Answer» Both Assertion and Reason are true and Reason is the correct EXPLANATION of Assertion. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion. Assertion is true but Reason is false. Both Assertion and Reason are false. SOLUTION :Both assertion and reason are correct and reason is correct explanation of assertion. A solution CONTAINING a mixture of acetic acid and the SODIUM acetate acts as a buffer solution as it maintains a constant value of pH (= 4.75) and its pH is not affected on addition of small amounts of acid or alkali.
