Sulfate Ion formula, also known as Sulfate anion formula or Sulfate dianion formula is explained in this article. It is a polyatomic anion and has an empirical formula SO4-2. It is a salt of sulfuric acid. The sulfate anion is a very weak base.
Most of the sulfates such as Na+, NH4+and K+ are soluble in water whereas white barium sulfate and white lead (II) sulfate are insoluble in water. It is a weak oxidizing agent and is obtained by deprotonation of OH groups of sulfuric acid (H2SO4). Sulphate salts, peroxides, and acid derivatives of sulfate have wide applications in industries.
