Equilibrium Question 203
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} $
