What happens when a piece of aluminium metal is added to dilute hydrochloric acid?
(N/A) When a piece of aluminium metal is added to dilute hydrochloric acid,a displacement reaction occurs. Aluminium is more reactive than hydrogen and lies above it in the reactivity series,so it displaces hydrogen from the dilute $HCl$ solution,resulting in the evolution of hydrogen gas.
The balanced chemical equation for this reaction is:
$2Al(s) + 6HCl(aq) \longrightarrow 2AlCl_3(aq) + 3H_2(g)$
The balanced chemical equation for this reaction is:
$2Al(s) + 6HCl(aq) \longrightarrow 2AlCl_3(aq) + 3H_2(g)$
