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.You need to login to perform this action.
