Periodic acid

The periodic acid is the molecule HIO₄ or H₅IO₆. The name of the molecule does not come from the word " période" , but of " iode" : periodic acid (to be compared with Iodic acid or Perchloric acid).

In diluted solution, the periodic acid exists in the shape of ions H⁺ and IO₄⁻. In higher concentration, the orthoperiodic acid , H₅IO₆, is formed. This one can be obtained in crystalline form. The acid orthoperiodic can be dehydrated in acid metaperiodic , HIO₄. A more increased heating led to the pentoxide formation of diiodure (I₂O₅) and Oxygen. apparently the Anhydride heptoxyde of diiodure does not exist in nature although it can be obtained by synthesis. Thus, two forms off periodates exist. One relating to the acid HIO_{4, the other relating to H5IO6. To form results in metaperiodates (meta- meaning less toilets) and to lath, orthoperiodates (ortho- meaning more toilets). Metaperiodates cuts solubilities and chemical properties similar to Perchlorate S (similar goal larger ion size) though they are less oxidizing than perchlorates.}

Structural Periodic acid is also used in organic chemistry for analysis. Periodic acid will cleave has local Diol into two Aldehyde fragments. This edge Be useful in determining the structure off Carbohydrates. --->
