    Carnal lite in solution (in \[{{H}_{2}}O\]), shows the properties of:

    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 mineral of the formula KCl. \[MgC{{l}_{2}}.6{{H}_{2}}O\]and thus in solution will show properties of \[{{K}^{+}},M{{g}^{2+}}\]and \[C{{l}^{-}}\] ions.
