用途と製造
UsesUsed as oxidizing agent (in acid solution) for manganese and organic compounds; [Merck Index]
General Manufacturing InformationPeriodic acid (HIO4), potassium salt (1:1): ACTIVE
応用分野
使用For 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.
一般的な説明Potassium (meta)periodate exhibits strong oxidizing properties in acidic medium.
調製方法
製造方法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.
Potassium periodate, KlO4, white solid, formed by electrolysis of potassium iodate under proper conditions.
純化方法Crystallise it from distilled water. Its solubility in H2O is 0.2% at 0o, 0.4% at 20o, 4.4% at 80o. and 7.9% at 100o. [Hill Inorg Synth I 171 1939, Schmeisser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 325 1963.]
