Peroxysulfuric Acid

(also called persulfuric acid), any of the oxy acids of sulfur that contain the peroxy group, —O—O—. Three peroxysulfuric acids are known: peroxymonosulfuric acid (H₂SO₅, also known as Caro’s acid), peroxydisulfuric acid (H₂ S₂ O₈), and peroxytrisulfuric acid (H₂ S₃ O₁₁). The most widely studied are H₂SO₅ and H₂S₂O₈; their salts, which are called peroxysulfates, have also been widely studied. In the free state, H₂SO₅ and H₂S₂O₈ occur as colorless crystals, with melting points of 45°C and 65°C, respectively; their aqueous solutions are obtained by electrolysis of sulfuric acid solutions. Peroxy- monosulfuric acid is a strong oxidizing agent that is used in organic synthesis. Peroxydisulfuric acid and its salts are also oxidizing agents, serving as sources of hydrogen peroxide (H₂O₂).
