Applications
Potassium metaperiodate is used as an oxidizing agent in organic synthesis and laboratory processes, particularly in the oxidation of diols to carbonyl compounds.
 
Description
Potassium periodate is an inorganic salt with the molecular formula KIO4. It is composed of a potassium cation and a periodate anion and may also be regarded as the potassium salt of periodic acid.
 
Preparation
Potassium periodate can be prepared by the oxidation of an aqueous solution of potassium iodate by chlorine and potassium hydroxide. It can also be generated by the electrochemical oxidation of potassium iodate, however the low solubility of KIO3 makes this approach of limited use.
 
Chemical Properties
Potassium metaperiodate is a crystalline compound known for its strong oxidizing properties, often used in analytical chemistry and organic synthesis for oxidation reactions.
 
Definition
It is composed of a potassium cation and a periodate anion and can also be viewed as the potassium salt of periodate. Note that the pronunciation is not periodic, but iodate. Unlike other common periodates such as sodium periodate and periodic acid, it is only available in the form of metaperiodate.
