In aqueous solution, we write $metathesis$ $"metathesis"$ , i.e. partner exchange...........

Explanation:

$M g (N O_{3}) (a q) + K_{2} S O_{4} (a q) \to M {g (S O_{4})}_{2} + 2 K N O_{3} (a q)$ $Mg(NO_3)(aq) + K_2SO_4(aq) rarr Mg(SO_4)_2 + 2KNO_3(aq)$

Neither the nitrate nor the sulfate salts are particularly insoluble......we would have an aqueous solution of all the ions......

$M {g (N O_{3})}_{2} (s) + K_{2} S O_{4} (s) H_{2} O - - \to M g^{2 +} + S O_{4}^{2 -} + 2 K^{+} + 2 N O_{3}^{-} (a q)$ $Mg(NO_3)_2(s) + K_2SO_4(s) stackrel(H_2O)rarr Mg^(2+)+ SO_4^(2-) + 2K^+ + 2NO_3^(-)(aq)$

ALL nitrates are soluble, and most SULFATES are soluble (except for those of $P b^{2 +}, H g_{2}^{2 +}, B a^{2 +}$ $Pb^(2+), Hg_2^(2+), Ba^(2+)$ ; $C a S O_{4}$ $CaSO_4$ is moderately soluble).

What would occur if I mixed $potassium sulfate$ $"potassium sulfate"$ with $barium nitrate$ $"barium nitrate"$ in aqueous solution?

There will be no reaction.

Explanation:

Is the following reaction possible?

${Mg(NO}_{3})_{2} + K_{2} {SO}_{4}$ $"Mg(NO"_3)_2 + "K"_2"SO"_4$ $\to$ $rarr$ ${MgSO}_{4} + {2KNO}_{3}$ $"MgSO"_4 + "2KNO"_3$

In order for this reaction to occur, one of the products must be an insoluble precipitate, an insoluble gas, or water. We can see that no water is produced and no insoluble gas is produced. So now we need to see if either of the products is an insoluble precipitate.

To determine if any of the products is an insoluble precipitate, we can consult a table of solubility rules.

According to the Solubility Table below, ${MgSO}_{4}$ $"MgSO"_4$ is soluble, and ${KNO}_{3}$ $"KNO"_3$ is soluble. Therefore, the reaction does not occur because all of the ions in the reactants remain dissolved in solution.
In order to indicate that there is no reaction, you show that the reactants yield no reaction.

${Mg(NO}_{3})_{2} (aq) + K_{2} {SO}_{4} (aq)$ $"Mg(NO"_3)_2("aq") + "K"_2"SO"_4("aq")$ $\to$ $rarr$ $no reaction$ $"no reaction"$
