MCQ
If ${K_{sp}}$ for $HgS{O_4}$ is $6.4 \times {10^{ - 5}},$ then solubility of the salt is
  • ✓
    $8 \times {10^{ - 3}}$
  • B
    $8 \times {10^{ - 6}}$
  • C
    $6.4 \times {10^{ - 5}}$
  • D
    $6.4 \times {10^{ - 3}}$
✓

Answer

Correct option: A.
$8 \times {10^{ - 3}}$
(a) $HgS{O_4}$ of ${K_{sp}} = {S^2}$

$S = \sqrt {{K_{sp}}} $ ; $S = \sqrt {6.4 \times {{10}^{ - 5}}} $; $S = 8 \times {10^{ - 3}}\,m/l$.
