Ammonium iodate is an inorganic salt which is sparingly soluble in cold, and moderately soluble in hot water, like all iodate salts, it is a strong oxidizer.
Ammonium iodate can be obtained by neutralising a solution of iodic acid with ammonia.[2]
Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt.
Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen triiodide is formed.
