context_page_description: Periodic acid is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. Like all periodates it can exist in two forms: orthoperiodic acid, with the chemical formula H₅IO₆ and metaperiodic acid, which has the formula HIO₄.
  Periodic acid was discovered by Heinrich Gustav Magnus and C. F. Ammermüller in 1833.
