By Mossbauer spectroscopy, one can determine the oxidation state of iron.

Vikas Yadav

Sandip Munshi Dear sir, in both Fe3O4 and Fe2O3, Fe will be in both oxidation states that is Fe+2 and Fe+3.

You can carry out the powder XRD (pXRD) experiment Vikas Yadav

Sandip Munshi thank you for your suggestion sir
