Question

Write the equation for the reaction of:

Iron with dilute hydrochloric acid.

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

Answer 1

Iron reacts slowly with cold, dilute hydrochloric acid to give iron (II) chloride and hydrogen gas.

\[\ce{\underset{Iron}{Fe_{(s)}} + \underset{Hydrochloric acid}{2HCl_{(aq)}} -> \underset{Iron (II) chloride}{FeCl2_{(aq)}} + \underset{Hydrogen}{H2_{(g)}}}\]
