Assertion (A): On mixing equal volumes of 1M Hci and 2 M CH_(3)COONa, an acidic buffer solution is formed.
Reason (R) : The resultant mixture contains CH_(3)COOH and CH_(3)COONa which are parts of acidic buffer.
A. If both (A) and (R) are correc, and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct but (R) is not the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If (A) is incorrect, but (R) is correct.

(A) is true:
{:(HCI+,CH_(3)COONa rarr,CH_(3)COOH+,NaCI),(1M,2M,1M,):}
[CH_(3)COONa]_("left") =2 -1 = 1 M.
So solution contains CH_(3)COOH and CH_(3)COONa, and acidic buffer forms (R) is true.
