Sodium iodate (NaIO3) is a chemical compound.

Additional recommended knowledge

Sodium iodate is an oxidizing agent and as such it can cause fires if in contact with combustible materials or reducing agents. It can be prepared by reacting a sodium-containing base such as sodium hydroxide with iodic acid, for example:

HIO3 + NaOH → NaIO3 + H2O

It can also be prepared by adding iodine to a hot, concentrated solution of sodium hydroxide.

3 I2 + 6 NaOH → NaIO3 + 5 NaI + 3 H2O

Conditions/substances to avoid are: heat, shock, friction, combustible materials, reducing materials, aluminum, organic compounds, carbon, hydrogen peroxide, sulfides.
