    If \[{{K}_{sp}}\]Ag \[A{{g}_{2}}C{{O}_{3}}\] is \[8\times {{10}^{-12}},\]the molar solubilty of \[A{{g}_{2}}C{{O}_{3}}\] in \[AgN{{O}_{3}}\] is:

    A) \[8\times {{10}^{-12}}M\]

    B) \[8\times {{10}^{-11}}M\]

    C) \[8\times {{10}^{-10}}M\]

    D) \[8\times {{10}^{-13}}M\]

    Correct Answer: C

    Solution :

    \[8\times {{10}^{-12}}={{(2S'+0.1)}^{2}}S'\] Or,        \[S'=8\times {{10}^{-10}}M.\]
