sodium hydroxide
The chemical formula for the sulfate ion is SO42-
So42-
Formula: SO32- and SO42-
Borin is B3+ and Sulfate is SO42- The chemical formula for the both would be B2(SO4)3
Ba2(SO4)2
The potassium ion is K+ and the sulfate ion is SO42-
SO4 This is a non-existent compound. There is an ion SO42- (sulfate ion) which does exist.
Hydrogen sulfite is the bisulfite anion, or HSO3-.Sulfite is SO32-.Do not confuse sulfite (SO32-) with sulfide (S2-), or sulfate (SO42-).
Sulphuric Acid No - H2SO4 is sulphuric acid. SO4 on its own like this is sulphur tetroxide SO4 2- would be the sulphate ion.
The chemical equation for sulfate (or sulphate) is SO42-
copper sulfate CuSO4
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.
