MCQ
Which of the following salts will give highest $pH$ in water?
  • A
    $KCl$
  • B
    $NaCl$
  • ✓
    $Na_2CO_3$
  • D
    $CuSO_4$
✓

Answer

Correct option: C.
$Na_2CO_3$
c
$\mathrm{Na}_{2} \mathrm{CO}_{3}$ which is a salt of $\mathrm{NaOH}(\text {strong base) and } \mathrm{H}_{2} \mathrm{CO}_{3}$ (weak acid) will produce a basic solution with $pH$ greater than $7.$
