A) 27
B) 3
C) 9
D) \[12\sqrt{3}\]
Correct Answer: D
Solution :
\[Ca{{(OH)}_{2}}\underset{s}{\mathop{C{{a}^{2+}}}}\,+\underset{2s}{\mathop{2O{{H}^{-1}}}}\,\] \[{{K}_{sp}}=[S]\,{{[2S]}^{2}}\] \[{{K}_{sp}}=4{{s}^{3}}\] \[{{K}_{sp}}=4{{\left( \sqrt{3} \right)}^{3}}=12\sqrt{3}\]You need to login to perform this action.
