This is a redox question. In order for Mg2+ to oxidize Fe(s), Mg2+ needs to have a higher reduction potential (tendency to be reduced) than Fe2+.

Mg2+ + 2 e− --> Mg(s) E° = −2.372 Volts

Fe2+ + 2 e− --> Fe(s) E° = −0.44 Volts (More favorable reaction)

Fe2+ has a higher reduction potential than Mg2+, so Mg+2 will not oxidize Fe(s).

Iron Sulfate can refer to either Fe2(SO4)3 or FeSO4. Both react with magnesium because magnesium is higher on the activity series of metals than iron.

FeSO4 + Mg [arrow] MgSO4 + Fe

Fe2(SO4)3 + 3Mg [arrow] 3MgSO4 + 2Fe
