The molecular formula for sulfate is SO42-. Four bonds, two single and two double, are shared between the sulfur and oxygen atoms. The -2 you see on the sulfate ion reminds you that this molecule is charged. This negative charge comes from the oxygen atoms that surround the sulfur atom
What is the charge for sulfate?
Charge on Sulfate Sulfate has a 2− charge. In order to understand why this polyatomic ion has a charge, the formal charge of one of the resonance structures can be observed. In the image below, the oxygen atom labeled 1 has 6 valence electrons.
Why is sulphate a charge of 2?
Sulfur can have either a partial positive charge or a partial negative charge. Hydrogen Sulfide = H2S, which can break down to H+ and HS- [sort of like water]. We would need 32 valence electrons for 4 full outer shells(8×4) but only have 30. Thus the charge is 2- for the ion.

What is the percentage of Sulphur in sulphate ion?
We may say sodium sulfate is 32.37% sodium, 22.57% sulfur, and 45.06% oxygen; or, 32.37% sodium and 67.63% sulfate. The total is 100% in either case. We now have two sets of numbers which show mass relationships among the elements in sodium sulfate: (1) the formula mass and (2) the percentage composition.
What is the name of the PO4 3?
PO43- is a chemical derivative of phosphoric acid with a chemical name Phosphate. Phosphate is also called Phosphate ion or Orthophosphate. It is a trivalent inorganic anion and a conjugate base of hydrogen phosphate.
How do you write sulfide?
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. Solutions of sulfide salts are corrosive.
What is sulphate and sulphide?
Sulphate and sulphite are the polyatomic ions of sulphur and are formed by the reaction of sulphur with oxygen atoms.
Is sulphur and sulphide same?
Sulphur is a chemical compound with the symbol S and has the atomic number 16. Sulphide is an inorganic anion of sulphur. It has the chemical formula S2-. Sulphur is sometimes found in the pure form but mostly occurs as sulphide or minerals of sulfate.
