Question

Can anyone tell me the preparation of FeCl3?
apart
from these
1.Dissolving pure iron in a solution of iron(III) chloride
Fe(s) + 2 FeCl3(aq) → 3 FeCl2(aq)
2.Dissolving iron ore in hydrochloric acid
Fe3O4(s) + 8 HCl(aq) → FeCl2(aq) + 2 FeCl3(aq) + 4 H2O

3.Oxidation of iron (II) chloride with chlorine
2 FeCl2(aq) + Cl2(g) → 2 FeCl3(aq)
4.Oxidation of iron (II) chloride with oxygen
4FeCl2(aq) + O2 + 4HCl → 4FeCl3(aq) + 2H2O

5.Reacting Iron with hydrochloric acid, then with hydrogen peroxide. The hydrogen peroxide is the oxidant in turning iron chloride into ferric cloride
