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

  • question_answer If the solubility of a sparingly soluble salt of the type \[B{{A}_{2}}\] (giving three ions on dissociation of a molecule) is \[x\] moles per litre, then its solubility product is given by       [BHU 1987]

    A)                 \[{{x}^{2}}\]

    B)                 \[2{{x}^{3}}\]

    C)                 \[4{{x}^{2}}\]    

    D)                 \[4{{x}^{3}}\]

    Correct Answer: D

    Solution :

               By formula \[B{{A}_{2}}\to {{B}^{+}}+2{{A}^{-}}\]                                 \[{{K}_{sp}}=4{{x}^{3}}\]
