Copper sulphate is a compound, not an element, and therefore has a formula, not a symbol. Unhydrated copper (II) sulfate has the formula CuSO4.
FeSo4
Fe (III)SO4
Ferric sulphate, or iron (III) sulphate has the formula Fe2(SO4)3.
FeSO4 and Fe2(SO4)3
Ferrous sulphate, or iron (II) sulphate has the formula FeSO4.
There are two kinds of iron sulfate: iron (II) sulfate has the formula FeSO4 and iron (III) sulfate has the formula Fe2(SO4)3.
The chemical formula for iron sulphate is dependent on the oxidation state of iron. For iron '2', it is FeSO4 For iron '3' , it is Fe2(SO4)3
Iron(ii)sulphate = FeSO4
The chemical formula for Iron Sulphate is FeSO4 So, there is Iron, Sulphur and Oxygen present.
Iron (II) sulphate has the formula FeSO4. The sulphate ion has a 2- charge, and the iron (II) ion has a 2+ charge, so only one of each ion is needed to form a neutral iron (II) sulphate compound.

The chemical formula for iron(II) sulphate is FeSO4, for iron(III) sulfate is Fe2(SO4)3 The formula for iron(II) sulfide is FeS, iron(III) sulfide Fe2S3
The chemical formula for Iron Sulphate is FeSO4 So, there is Iron, Sulphur and Oxygen present.
B2(SO4)3 is boron sulphate.
