Potassium periodate

From Wikipedia, the free encyclopedia

Potassium periodate has formula KIO₄.

Density is 3.618 g cc^-1. It melts at 581.85 °C. It is slightly soluble in water (one of the less soluble of potassium salts, owing to a large anion), giving rise to a solution that is slightly alkaline. On heating (especially with manganese(IV) oxide as catalyst), it decomposes to form potassium iodate, releasing oxygen gas. The low solubility of KIO₄ makes it useful for the determination of potassium.
