Sodium iodate

Sodium iodate (NaIO3) is a chemical compound.

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.
