JEE Main & Advanced Chemistry Equilibrium Question Bank Common ion effect, Isohydric solutions, Solubility product, Ionic product of water and salt hydrolysis

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

    A)                 27          

    B)                 3

    C)                 9             

    D)                 \[12\sqrt{3}\]

    Correct Answer: D

    Solution :

    \[Ca{{(OH)}_{2}}\]⇌\[\underset{(S)\,}{\mathop{C{{a}^{++}}}}\,+\underset{{{(2S)}^{2}}}{\mathop{2O{{H}^{-}}}}\,\]                                  \[{{K}_{sp}}=4{{S}^{3}}=4\times \sqrt{3}\times \sqrt{3}\times \sqrt{3}=12\sqrt{3}\]
