Aluminium reacts with dilute hydrochloric acid to give aluminum chloride and hydrogen gas.
The balanced equation is = 2Al(s) + 6HCl(aq) -----> 2AlCl3(aq) + 3H2(g).
When a piece of aluminium metal is added to dilute hydrochloric acid, the result is two products - an aqueous product and a gaseous product.
