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. $C{H_3}COOH + C{H_3}COONa$
