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. ==References== {{Unreferenced|date=September 2007}} <references/> [[Category:Iodates]] [[Category:Sodium compounds]] [[Category:Inorganic compound stubs]] {{inorganic-compound-stub}} [[ar:يودات صوديوم]]
