Peroxymonosulfuric acid, also known as persulfuric acid, peroxysulfuric acid is the inorganic compound with the formula H₂SO₅. It is a white solid. It is a component of Caro's acid, which is a solution of peroxymonosulfuric acid in sulfuric acid containing small amounts of water. Peroxymonosulfuric acid is a very strong oxidant (E⁰ = +2.51 V).
