Question 5.3
Translate the following statement into chemical equation and then balance it:

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

Answer 1

The chemical equation for the given chemical reaction is:
${\text{BaCl}}_2\text{(aq)}+{\text{Al}}_2{\text{(SO}}_4{)}_3\text{(aq)}\to {\text{AlCl}}_3\text{(aq)}+{\text{BaSO}}_4\text{(s)}$

The balanced chemical equation is:
$3{\text{BaCl}}_2\text{(aq)}+{\text{Al}}_2{\text{(SO}}_4{)}_3\text{(aq)}\to 2{\text{AlCl}}_3\text{(aq)}+3{\text{BaSO}}_4\text{(s)}$
