Ferric sulphate, or iron (III) sulphate has the formula Fe2(SO4)3.
Ferrous sulphate, or iron (II) sulphate has the formula FeSO4.
The molecular formula for Ammonium Sulphate is (NH4)2SO4.
CrSO4
Calcium forms divalent cations and sulphate forms divalent anions. Therefore, the formula unit contains only one of each ion and has the formula CaSO4.
Iron(II) sulphate Chemical formula is FeSO4 The molecular weight is 151,908 g (for the anhydrous salt)
The chemical formula of sodium sulfate is Na2SO4.
The formula for ferrous sulphate is FeSO4.
The molecular formula of ammonium sulfate is (NH4)2SO4. This is derived using the criss-cross method, which involves crossing the numerical charges of the ions to determine the subscript for each element in the compound.
The Chemical Formula for Nickel Sulphate is NiSO4.
The chemical formula of ferrous sulphate is FeSO4.
The chemical formula for ferrous sulfate is FeSO4.
