Answer When iron is heated in a stream of dry chlorine the product is iron(III) chloride. This happens because chlorine is a powerful oxidising agent so brings out the higher oxidation state of iron:$$ 2Fe _{(s)} + 3Cl_{2_{(g)}} \rightarrow 2FeCl_{3_{(s)}} $$ To make iron(II) chloride you can react XS iron with dilute hydrochloric acid: $$Fe_{(s)} + 2HCl_{(aq)} \rightarrow FeCl_{2} + h_{2 _{(g)}} $$
