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

  • question_answer If \[S\] and \[{{K}_{sp}}\] are respectively solubility and solubility product of a sparingly soluble binary electrolyte, then [CPMT 1988; MP PMT 1999]

    A)                 \[S={{K}_{sp}}\]               

    B)                 \[S=K_{sp}^{2}\]

    C)                 \[S=\sqrt{{{K}_{sp}}}\] 

    D)                 \[S=\frac{1}{2}{{K}_{sp}}\]

    Correct Answer: C

    Solution :

               For a binary electrolyte, so that                    \[{{K}_{sp}}=S\times S={{S}^{2}}\]                                 \[S=\sqrt{{{K}_{sp}}}\].
