Which of the following mixtures forms an acid buffer
- A$NaOH + HCl$
- ✓$C{H_3}COOH + C{H_3}COONa$
- C$N{H_4}OH + N{H_4}Cl$
- D${H_2}C{O_3} + {(N{H_4})_2}C{O_3}$
✓
Answer
Correct option: B.
$C{H_3}COOH + C{H_3}COONa$
(b) An acid buffer solution consists of a weak acid and its salt with strong base. i.e. $C{H_3}COOH + C{H_3}COONa$
