Question

By using iron metal only, how will you prepare:

Iron (II) Chloride.

Answer 1

• When iron reacts with dilute hydrochloric acid ($\mathrm{HCl}$) then ferrous chloride or iron (II) chloride (${\mathrm{FeCl}}_2$) forms with the evolution of hydrogen gas.

The balanced equation is:

$$\begin{gathered} {\mathrm{Fe}}_{\left(\mathrm{s}\right)}+2{\mathrm{HCl}}_{(\mathrm{dil}.)}\to {\mathrm{FeCl}}_{2\left(\mathrm{s}\right)}+{\mathrm{H}}_{2\left(\mathrm{g}\right)} \\ \mathrm{Iron}\mathrm{Hydrochloric}\mathrm{Iron}\left(\mathrm{II}\right)\mathrm{Hydrogen} \\ \mathrm{acid}\mathrm{chloride} \end{gathered}$$
