Use

Potassium periodate (chemical formula: KIO4) is a kind of inorganic salt composed of a potassium cation and a periodate anion. It can be used for the determination of potassium and cerium owing to its low solubility of KIO4. It can be used an oxidizing agent, and as a source of oxygen. It can also be used for the determination of the concentration of other compounds through measuring the reaction between DPC (sc-202590) and KIO4. It can be synthesize through the oxidation of potassium iodate through chlorine and potassium hydroxide, or by the electrochemical oxidation of potassium iodate.
