Nothing if the oxidation state of iron in the 'Iron Sulfate' is +2.

Explanation:

Ferrous ion => +2 oxidation state => #FeSO_4# => Ferrous Sulfate => Iron (II) Sulfate
Ferric ion => +3 oxidation state => #Fe_2(SO_4)_3# => Ferric Sulfate => Iron (III) Sulfate

The issue is, one needs to ID oxidation state of the variable charged element by putting it's oxidation state value in roman numerals in parenthesis following the name of the element. For metals ending in -ous the identity is the lower oxidation state of the two elements while names ending in -ic refer to the higher oxidation states.
