    \[{{K}_{sp}}\] value of \[Al\,{{(OH)}_{3}}\] and \[Zn\,{{(OH)}_{2}}\] are  \[8.5\times {{10}^{-23}}\]and \[1.8\times {{10}^{-14}}\] respectively. If \[N{{H}_{4}}OH\] is added in a solution of  \[A{{l}^{3+}}\]and \[Z{{n}^{2+}},\] which will precipitate earlier                 [MP PMT 1989; CPMT 1989]

    A)                 \[Al\,{{(OH)}_{3}}\]        

    B)                 \[Zn\,{{(OH)}_{2}}\]

    C)                 Both together  

    D)                 None

    Correct Answer: A

    Solution :

                    Solubility of \[Al{{(OH)}_{3}}\] is lesser than \[Zn{{(OH)}_{2}}\].
