| PERIODIC ACID Usage And Synthesis |
| Chemical Properties | PERIODIC ACID is colourless crystals
| | Physical properties | In
dilute solution, periodic acid exists as H+ and IO4-.
When more concentrated, orthoperiodic acid, H5IO6, is
formed. Note that this compound is essentially a dihydrate,
HIO4·2H2O. This can be obtained as a crystalline
solid. O-periodic acid can be dehydrated to metaperiodic
acid, m-HIO4. Further heating gives di-iodine pentoxide
(I2O5) and O2. The anhydride di-iodine heptoxide,
i.e. I2O7, does not exist in nature but can be formed
synthetically. | | Uses | PERIODIC ACID is used as an oxidiser and in the determination of manganese.
| | Uses | In organic synthesis. | | Uses | Periodic acid is used as a component for glycoprotein stains. It serves as a pharmaceutical and synthetic intermediate and is used in silk screen printing. It acts as an oxidizing agent especially the cleavage of 1,2 diols to prepare dialdehydes. It has selective oxidation powers which makes it an ideal reagent for the reclamation of silk screens in the printing industry. It finds application in life sciences for the analysis of intracellular polysaccharides like glycogen, starch and cellulose. Furthermore, it is used in the oxidation reactions converting sulfides into sulfones, catalyzed by chromium(VI) oxide and oxidation reactions converting alcohols to aldehydes and ketones. | | Reactions | Paraperiodic acid H5IO6, is obtained from sodium paraperiodate, formed by action of chlorine upon a NaOH solution containing I2. On vacuum drying, paraperiodic acid yields metaperiodic acid, HIO4, and dimesoperiodic acid, H4I2O9; which form heteropoly acids with a number of oxides and acids. The periodic acids and their salts are strong oxidizing agents both with inorganic and organic compounds. | | General Description | Periodic acid (H5IO6) is an oxoacid of iodine. It is commonly used as an oxidizing agent in organic synthesis for the preparation of useful chemical intermediates. Periodic acid is also used in oxidative cleavage reactions. | | Flammability and Explosibility | Notclassified |
