    What is the minimum concentration of \[S{{O}_{4}}^{2-}\]required to precipitate \[BaS{{O}_{4}}\] in a solution containing \[1.0\times {{10}^{-4}}\] mole of\[B{{a}^{2+}}\]? \[{{K}_{sp}}\] for \[BaS{{O}_{4}}=4\times {{10}^{-10}}\]

    A) \[4\times {{10}^{-10}}M\]        

    B) \[2\times {{10}^{-7}}M\]

    C) \[4\times {{10}^{-6}}M\]         

    D) \[2\times {{10}^{-3}}M\]

    Correct Answer: C

    Solution :

    [c] \[[B{{a}^{2+}}][SO_{4}^{2-}]\] \[{{K}_{sp}}=(1.0\times {{10}^{-4}})[SO_{4}^{2-}]=4\times {{10}^{-10}}\] \[\therefore [SO_{4}^{2-}]=4\times {{10}^{-6}}M\]
