It dissolves in water very well, but it also exists in the pure state, as opposed to chloric acid or bromic acid. Iodic acid contains iodine in the oxidation state +5 and it is one of the most stable oxo-acids of the halogens in its pure state. When iodic acid is carefully heated, it dehydrates to iodine pentoxide. On subsequent heating, the iodine pentoxide further decomposes, giving a mix of iodine, oxygen and lower oxides of iodine. ==Preparation== Iodic acid can be produced by oxidizing I2 with strong oxidizers such as Nitric acid , Chlorine , Chloric acid or Hydrogen peroxide ,〔 Arnold F.
