Periodic acid - Wikipedia

WebbPeriodic acid is the highest oxoacid of iodine, in which the iodine exists in oxidation state VII. Like all periodates it can exist in two forms: orthoperiodic acid, with the chemical formula H 5 IO 6 and metaperiodic acid, which has the formula HIO 4. Periodic acid was discovered by Heinrich Gustav Magnus and C. F. Ammermüller in 1833.
