Periodic acid was discovered by Heinrich Gustav Magnus and C. F. Ammermüller in 1833. [3] Synthesis [ edit ]

Periodate is part of a series of oxyacids in which iodine can assume oxidation states of −1, +1, +3, +5, or +7. A number of neutral iodine oxides are also known.H 5 IO 6 + H + + 2 e − ⟶ IO 3 − + 3 H 2 O {\displaystyle {\ce {H5IO6 + H+ + 2e- -> IO3- + 3 H2O}}} E° = 1.6 V [5]

Record of Natriumperiodat in the GESTIS Substance Database of the Institute for Occupational Safety and Health, accessed on 2018-01-08. Classically, periodate was most commonly produced in the form of sodium hydrogen periodate ( Na 3H 2IO 6). [2] This is commercially available, but can also be produced by the oxidation of iodates with chlorine and sodium hydroxide. [3] Or, similarly, from iodides by oxidation with bromine and sodium hydroxide:

Periodic acid ( / ˌ p ɜːr aɪ ˈ ɒ d ɪ k/ per-eye- OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H 5IO 6, and metaperiodic acid, which has the formula HIO 4. Now charges are reduced. But, if possible, we can try to reduce charges furthermore to obtain the best lewisIf charges exist on atoms, they should be marked on now. Marking charges of atoms is important because it is Ammermüller, F.; Magnus, G. (1833). "Ueber eine neue Verbindung des Jods mit Sauerstoff, die Ueberjodsäure".
