MCQ

Which buffer solution out of the following will have $pH > 7$

A
$C{H_3}COOH + C{H_3}COONa$
B
$HCOOH + HCOOK$
C
$C{H_3}COON{H_4}$
✓
$N{H_4}OH + N{H_4}Cl$

✓

Answer

Correct option: D.

$N{H_4}OH + N{H_4}Cl$

d
A solution that resists change in $pH$ value upon addition of small amount of strong acid or base (less than $1 \,\%$ ) or when solution is diluted is called buffer solution.

Basic buffer solution : A basic buffer solution consists of a mixture of a weak base and its salt with strong acid. The best known example is a mixture of $NH _4 OH$ and $NH _4 Cl$.
