Question

Write the equation for the reaction of:

Aluminium with dilute hydrochloric acid.

Name the products formed in the given case. Also indicate the physical states of all the substances involved.

Answer 1

Aluminium metal reacts rapidly with dilute hydrochloric acid to form aluminium chloride and hydrogen gas.

\[\ce{\underset{Aluminium}{2Al_{(s)}} + \underset{Hydrochloric acid}{6HCl_{(aq)}} -> \underset{Aluminium chloride}{2AlCl3_{(aq)}} + \underset{Hydrogen}{3H2_{(g)}}}\]
