# What occurs when magnesium chloride and sodium sulfate react in aqueous solution?

Dec 22, 2016

Neither salt, or the salt formed from exchange is particularly insoluble in water.

#### Explanation:

In aqueous solution, you would form $M {g}^{2 +}$, $C {l}^{-}$, $N {a}^{+}$, and $S {O}_{4}^{2 -}$ ions. These would tend to remain in solution, as the ion exchange salts are soluble. A better question would be the mixture of barium chloride and sodium sulfate in that barium forms a water insoluble sulfate:

$B a C {l}_{2} \left(a q\right) + N {a}_{2} S {O}_{4} \left(a q\right) \rightarrow B a S {O}_{4} \left(s\right) \downarrow + 2 N a C l \left(a q\right)$

Else,

$B {a}^{2 +} + S {O}_{4}^{2 -} \rightarrow B a S {O}_{4} \left(s\right) \downarrow$
