용도For the colorimetric determination of Mn (oxidizes manganese compounds to permanganates), as oxidizing agentPotassium periodate is used as an oxidizing agent in organic synthesis and an analytical reagent for the determination of potassium and cerium. It is also used in colorimetric estimation of manganese. It reacts with ammonium cerium(IV) nitrate to prepare tris[trinitratocerium(IV)] paraperiodate which finds application as an oxidant.
일반 설명Potassium (meta)periodate exhibits strong oxidizing properties in acidic medium.
Potassium periodate can be prepared by oxidation of potassium iodate with a powerful oxidizing agent such as potassium permanganate, chlorine or bromine in basic solution:IO3ˉ+ Cl2+ 2OHˉ→IO4ˉ+ 2Clˉ+ H2OAlso, the salt may be prepared by electrolysis.
생산 방법Potassium periodate, KlO4, white solid, formed by electrolysis of potassium iodate under proper conditions.
