Applications

Potassium 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.

Notes

Hygroscopic. Incompatible with strong reducing agents, powdered metals and amines.
