Peroxysulfate

(also called persulfate), any salt of the peroxysulfuric acids. Peroxymonosulfuric acid (H₂SO₅) forms acid salts, for example, NaHSO₅, and neutral salts, for example, Na₂SO₅. Acid salts are good bleaching agents, while no practical application has as yet been found for neutral salts. Peroxydisulfuric acid (H₂S₂O₈) forms only neutral salts, the most widely used being (NH₄)₂S₂O₈ and K₂S₂O₈. The latter salt is used to prepare solutions of hydrogen peroxide (H₂O₂); it is also an oxidizing agent, a polymerization initiator, and a bleach for fats and soaps.
