High Quality Content by WIKIPEDIA articles! Periodic acid, or iodic(VII) acid is an oxoacid of iodine having chemical formula HIO4 or H5IO6. In dilute solution, periodic acid exists as H+ and IO4 . When more concentrated, orthoperiodic acid, H5IO6, is formed. This can be obtained as a crystalline solid. Orthoperiodic acid can be dehydrated to metaperiodic acid, HIO4. Further heating gives diiodine pentoxide (I2O5) and oxygen. The anhydride diiodine heptoxide does not exist in nature but can be formed synthetically. Thus, two forms of periodates exist. One relating to the acid HIO4, the other relating to H5IO6. The former results in metaperiodates (meta- meaning less water) and the latter, orthoperiodates (ortho- meaning more water). Metaperiodates have solubilities and chemical properties similar to perchlorates (similar but larger ion size) though they are less oxidizing than perchlorates.
