Answer:
Depends on the valency of the iron
There is iron(III) and there is iron(II) or iron (3) and iron(2) respectively
Iron(2) sulphate is FeSO4
Iron(3) sulphate is Fe2(SO4)3
Explanation:
Valency is the combining power of an element
Sulphate has -2 valency
Iron(2) has +2
Iron(3) has +3 valency
The reason for variable valency is that some elements differ in their capacity to combine with other elements depending on the nature of the reaction.
