Barium sulphate or Barium sulfate is a neutral chemical compound formed of barium and sulphate or sulfate ions. Typically, a chemical compound has sulfate or sulphate to its name when it consists of a sulphate anion which is a polyanion formed of sulfur and oxygen. The sulphate polyanion has the molecular formula as SO 4 2-and the electrical charge present on the sulphate anion is -3.
