Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(c,d)
HNO 3 + CH 3 COONa mixture can act as buffer solution if volume of HNO 3 solution taken is lesser than volume of CH 3 COONa solution because of following reaction :
CH 3 COONa + HNO 3 ⎯→ CH 3 COOH + NaNO 3
CH 3 COOH + CH 3 COONa - mixture will act as buffer.
