Detailed Product Description:

Periodic Acid, or more precisely, Orthoperiodic Acid (H₅IO₆) as it

is most commonly found, is a white, crystalline, hygroscopic powder,

freely soluble in water and alcohol.  It is most commonly derived by

interaction of iodine and concentrated perchloric acid.

Grade/Brand:

This is ACS Reagent Grade material with minimum 99% purity.

Background:

Contrary to common understanding, the name is not derived from

"period" or “periodical”, but from “per” as in perchloric and "iodine"

giving us “iodic” and it should thus be pronounced per-iodic.

The progression of the iodine family gives Iodic acid (HIO3), and

two Periodic acids: Metaperiodic acid (HIO₄) and Orthoperiodic

acid (H₅IO₆).  Orthoperiodic acid can be further dehydrated to

Metaperiodic acid, HIO₄.  Upon further heating diiodine pentoxide (I₂O₅)

and oxygen are formed.

Thus, two forms of periodates exist.  One relating to HIO₄, and 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.

Applications:

The Periodic acids and their salts (potassium iodate and sodium iodate) are

used as powerful oxidizing agents in organic synthesis.  Periodic acid cleaves a

vicinal glycol into two aldehydes, which is applicable in the structural analysis

of carbohydrates.

Precautions:

Strong irritant to eyes and skin.  Toxic by inhalation and ingestion.
