The chemical equation is

$3"BaCl"_2 (aq) + "Al"_2("SO"_4)_3 (aq) -> 3"BaSO"_4 (s) + 2"AlCl"_3 (aq)$

Barium Sulfate ( $"BaSO"_4$ ) being highly insoluble, will form a white precipitate.

A white precipitate of barium sulfate.

$3BaCl_2(aq) + Al_2(SO_4)_3(aq) rarr 3BaSO_4(s)darr +2AlCl_3(aq)$

Barium sulfate is quite insoluble in aqueous solution, $K_(sp) =1.08xx10^-10$ .

Alternatively, because the aluminum salts are along for the ride, we could write the net ionic equation:

$Ba^(2+) + SO_4^(2-) rarrBaSO_4(s)darr$
