    Which reagent is used to remove \[SO_{4}^{-}\]and \[C{{l}^{-}}\] [Pb. PMT 2002]

    A) \[BaS{{O}_{4}}\]

    B) \[NaOH\]

    C) \[Pb{{(N{{O}_{3}})}_{2}}\]

    D) KOH

    Correct Answer: C

    Solution :

    \[PbS{{O}_{4}}\]and \[PbC{{l}_{2}}\] are insoluble in cold water hence the reagent \[Pb{{(N{{O}_{3}})}_{2}}\]is used to remove \[SO_{4}^{2-}\]and \[C{{l}^{-}}\]
