Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate.

Translate the following statement into a chemical equation and then balance it:

Barium chloride solution reacts with aluminium sulphate solution to form a precipitate of barium sulphate and aluminium chloride solution.

Answer 1

\[\ce{BaCl2_{(aq)} + Al2(SO4)3_{(aq)} -> AlCl3_{(aq)} + BaSO4_{(s)}}\]

Balanced equation:

\[\ce{3BaCl2_{(aq)} + Al2(SO4)3_{(aq)} -> 2AlCl3_{(aq)} + 3BaSO4_{(s)}}\]
