Question

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

Solution of barium chloride and aluminium sulphate in water react to give insoluble barium sulphate and the solution of aluminium chloride.

Answer 1

1. The chemical equation for the reaction between barium chloride \[\ce{(BaCl2)}\] and aluminium sulphate \[\ce{(Al2(SO4)3)}\] in water is:
   \[\ce{BaCl2_{(aq)} + Al2(SO4)3_{(aq)} -> BaSO4_{(s)} + 2AlCl2_{(aq)}}\]
2. To balance the equation, ensure the number of each type of atom is equal on both sides. A balanced equation is:
   \[\ce{3BaCl2_{(aq)} + Al2(SO3)3_{(aq)} -> 3BaSO4_{(s)} + 2AlCl2_{(aq)}}\]
   These balanced chemical equations represent the reactions described in the given statement.
