Question: If solubility of calcium hydroxide is $ \sqrt{3} $ , then its solubility product will be [MH CET 2002]

Options:

A) 27

B) 3

C) 9

D) $ 12\sqrt{3} $

Show Answer

Answer:

Correct Answer: D

Solution:

$ Ca{{(OH)}_2} $ ⇌ $ \underset{(S),}{\mathop{C{a^{++}}}},+\underset{{{(2S)}^{2}}}{\mathop{2O{H^{-}}}}, $

$ K _{sp}=4S^{3}=4\times \sqrt{3}\times \sqrt{3}\times \sqrt{3}=12\sqrt{3} $
