Question

Explain the following reaction with the balanced equation.

Aluminium reacts with dil hydrochloric acid

Answer 1

When aluminium is treated with dilute hydrochloric acid, it forms aluminium chloride with release of hydrogen gas.

\[\ce{\underset{\text{Aluminium}}{2Al_{(s)}} + \underset{\text{Hydrochloric acid}}{6HCl_{(aq)}} -> \underset{\text{Aluminium chloride}}{2AlCl_{3(aq)}} + \underset{\text{Hydrogen}}{3H2↑}}\]
