General description
Periodic acid (H5IO6) is a colorless crystalline solid. It is widely employed as an oxidant and is weakly acidic in nature. It can be synthesized from iodic(V) acid.
Application
Periodic acid may be used in the synthesis of diiodine heptoxide (I2O7). It may be used in the Periodic acid Schiff staining procedures.
