Derivation of magnetic iron oxide (Fe3O4) where Fe=2+ and O= 2- |
|
Answer» tion:generally Fe3o4 is a mixed oxide,composed of two OXIDES Feo and Fe2o3 In Feo oxidizing state is +2 In Fe2o3 oxidizing state is +3 THEREFORE for calculating oxidizing state of Fe3o4 we TAKE the averages of both constituent oxides therefore o.s of Fe3o4 is 3+2/2=2.5also you could recognise that Feo+Fe2o3=Fe3o4 (in terms of NUMBER of atoms) I hope you understand this |
