Sodium iodate
Sodium iodate (NaIO3) is the sodium salt of iodic acid. Sodium iodate is an oxidizing agent. It has several uses. Preparation
It can be prepared by the reacting a sodium-containing base such as sodium hydroxide with iodic acid, for example:
HIO3 + NaOH → NaIO3 + H2O

Iodine pentoxide
This iodine oxide is the anhydride of iodic acid, and the only stable oxide of iodine. It is produced by dehydrating iodic acid at 200 °C in a stream of dry air:
2HIO3 → I2O5 + H2O
Structure
I2O5 is bent with an I–O–I angle of 139.2°,
