    Carnallite in solution in \[{{H}_{2}}O\], shows the properties of [DCE 2003]

    A) \[{{K}^{+}},M{{g}^{2+}},C{{l}^{-}}\]

    B) \[{{K}^{+}},C{{l}^{-}},SO_{4}^{2-},B{{r}^{-}}\]

    C) \[{{K}^{+}},M{{g}^{2+}},CO_{3}^{2-}\]

    D) \[{{K}^{+}},M{{g}^{2+}},C{{l}^{-}},B{{r}^{-}}\]

    Correct Answer: A

    Solution :

    Carnallite is a double salt with molecular formula \[KCl\].\[MgC{{l}_{2}}.6{{H}_{2}}O\]. It gives \[{{K}^{+}},M{{g}^{2+}}\] and \[C{{l}^{-}}\] ions in solution.
