Iodic Acid

Iodic Acid has the composition of HIO;), and forms transparent six-sided crystals soluble in water. It may be prepared by the action of nitric acid upon iodine, and by other chemical reactions.

It forms well-defined salts, called iodates, of which the greater number are insoluble. Sodium iodate frequently occurs associated with Chili, saltpetre (q.v.), and on this account the acid is sometimes found as an impurity in nitric acid prepared from this source. Neither the acid nor its salt are of any great practical importance.
