In dilute solution, periodic acid exists as H+ and IO4-.When more concentrated, orthoperiodic acid, H5IO6, is formed. This can be obtained crystalline.Orthoperiodic acid can be dehydrated to '''metaperiodic acid''', HIO4. Further heating gives Diiodine Pentoxide and Oxygen ; apparently the Anhydride 'diiodine heptoxide' doesn't exist in nature but can be formed synthetically. As we can see, 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- more water). Metaperiodates have solubilities and chemical properties similar to Perchlorate s (similar but larger ion size) though it is less oxidizing than perchlorates. |
