When you mix them dry, nothing. When you dissolve them in water, barium sulfate precipitates out and sodium chloride remains in solution. This is called a double decomposition reaction.

The explanation for this is neatly illustrated by the example given, barium chloride and sodium sulphate. In solution, neither of these compounds can really be said to exist - it is a sea of Na+ and Ba+ ions, and Cl- and SO4- ions, constantly changing partners. But when a barium ion happens to hook up with a sulfate ion, its solubility is so low that it immediately precipitates out, until all that are left in solution are sodium and chlorine ions.
