Substances that are stronger oxidising agents than ferrous ions can oxidise ferrous ions.
Fe2+ → Fe3+ + e-1
\(E^{\ominus}\) = - 0.77 V
This implies that the substances having higher reduction potentials than +0.77 V can oxidise ferrous ions to ferric ions. Three substances that can do so are F2, Cl2, and O2.
