'''Sodium iodate''' ([[Sodium|Na]][[Iodine|I]][[Oxygen|O<sub>3</sub>]]) 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:
[[Iodic acid|HIO<sub>3</sub>]] + [[Sodium hydroxide|NaOH]] → NaIO<sub>3</sub> + [[Water|H<sub>2</sub>O]]
It can also be prepared by adding [[iodine]] to a hot, concentrated solution of sodium hydroxide.
3 [[iodine|I<sub>2</sub>]] + 6 [[sodium hydroxide|NaOH]] → NaIO<sub>3</sub> + 5 [[sodium iodide|NaI]] + 3 [[water|H<sub>2</sub>O]]
Conditions/substances to avoid are: [[heat]], [[Shock (mechanics)|shock]], [[friction]], combustible materials, reducing materials, [[aluminium]], [[organic compounds]], [[carbon]], [[hydrogen peroxide]], [[sulfide]]s.
