  • question_answer
    Solubility of \[M{{X}_{2}}\] type electrolyte is \[0.5\times {{10}^{-4}}mole/litre\]. The value of \[{{K}_{sp}}\] of the electrolyte is [CBSE PMT 2002]

    A)                 \[5\times {{10}^{-13}}\]               

    B)                 \[25\times {{10}^{-10}}\]

    C)                 \[1.25\times {{10}^{-13}}\]         

    D)                 \[5\times {{10}^{12}}\]

    Correct Answer: A

    Solution :

               \[M{{X}_{2}}\] ⇌ \[\underset{(S)\,\,\,\,\,\,}{\mathop{{{M}^{2+}}}}\,+\,\underset{{{(2S)}^{2}}\,\,}{\mathop{2{{X}^{-}}}}\,\]; \[4{{S}^{3}}=4\times {{(0.5\times {{10}^{-4}})}^{3}}\]                                 \[=5\times {{10}^{-13}}\]
