Question 3

What happens when dilute hydrochloric acid is added to iron filings?

Answer 1

When dilute hydrochloric acid reacts with iron filings, iron chloride or ferrous(II) chloride is formed and hydrogen gas is liberated. The reaction involved is:

$\text{Fe(s)}+2\text{HCl(aq)}\to {\text{FeCl}}_2\text{(aq)}+{\text{H}}_2\text{(g)}$
