    When \[HCl\] gas is passed through saturated solution of \[BaC{{l}_{2}}\], a white ppt. is obtained. This is due to [CPMT 1979]

    A) Impurities in \[BaC{{l}_{2}}\]

    B) Impurities in \[HCl\]

    C) Precipitation of \[BaC{{l}_{2}}\]

    D) Formation of complex

    Correct Answer: C

    Solution :

    White precipitate obtained is of \[BaC{{l}_{2}}\], as the \[C{{l}^{-}}\] ion?s concentration increases due to the addition of HCl, the ionic product becomes more than solubility product and thus, BaCl2 is precipitated
