Iodic Acid, Hio3

Iodic Acid, Hio₃

a strong inorganic acid. In the free state, iodic acid is a crystalline substance with a melting point of 110°C. It is highly soluble in water. Upon heating to 200°C it loses water and is converted into the anhydride I₂O₅. Iodic acid is obtained according to the reaction 3I₂ + IOHNO₃ = 6HIO₃ + 10NO + 2H₂O (at 70°−80^oC). Its salts (iodates), which are strong oxidizing agents, decompose when heated to 400°C. Iodine is precipitated out during interaction with iodides in the presence of acids: KIO₃ + 5KI + 3H₂SO₄ = 3I₂ + 3K₂SO4 + 3H₂0. Iodates are obtained upon interaction of iodine with hot caustic alkaline solutions or during the oxidation of iodides; iodates are used as chemical reagents.
