The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
The Ferrous ion has a '2+' charge. Hence the formula for ferrous sulphate is FeSO4. NB The Ferric ion has a '3+' charge. Hence the formula for ferric sulphate is Fe2(SO4)3
The sulfate ion is a polyatomic anion with the empirical formula SO42− and a molecular mass of 96.06 daltons
it is same as ammonium sulphate, (NH4)2SO4
A sulphide is a simple chemical combination of an element and the Sulphur atom e.g. Hydrogen Sulphide, H2S. A sulphite is a chemical combination of an element and a compound of Sulphur and Oxygen, namely 3 Oxygen atoms to every Sulphur atom. E.g. Calcium Sulphite CaSO3.
The formula of the sulphate ion is SO42-
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
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 Ferrous ion has a '2+' charge. Hence the formula for ferrous sulphate is FeSO4. NB The Ferric ion has a '3+' charge. Hence the formula for ferric sulphate is Fe2(SO4)3
the chemical formula of zinc sulphate is ZnSO4.
Chromium VI sulphate Cr(SO4)3
There is no "formula, just the symbol Cr(VI) or CrVI.
The sulfate ion is a polyatomic anion with the empirical formula SO42− and a molecular mass of 96.06 daltons
Calcium forms divalent cations and sulphate forms divalent anions. Therefore, the formula unit contains only one of each ion and has the formula CaSO4.
No
The chemical formula of the ion sulfate is (SO4)2-.
it is same as ammonium sulphate, (NH4)2SO4
