let me try but i m not that sure if i m right . Iron Flouride is partly ionic and oil is non polar , FeF2 should not be soluble in oil if it s solid . if it s liquid in aqueous phase , it is a solution with Fe2+ and Cl- . when mixed with oil , 2 layers are seen .
i have a question here whether iron flouride is ionic enough to be saparated in oil because it has covalent property too
