MCQ
The solubility of $Ca{F_2}$ is a moles/litre. Then its solubility product is …..
  • A
    ${s^2}$
  • ✓
    $4{s^3}$
  • C
    $3{s^2}$
  • D
    ${s^3}$
✓

Answer

Correct option: B.
$4{s^3}$
(b) $Ca{F_2}⇌\mathop {C{a^{ + 2 }}}\limits_{(S)\,\,\,} + \mathop {2{F^ - }}\limits_{{{(2S)}^2}\,\,} $; ${K_{sp}} = 4{S^3}$
