Preparation and uses of Iodic acid (HIO₃),potassium salt (2:1): it can be prepared by iodine and potassium chlorooate. The pH value of the reaction solution is 1-2. And the reaction temperature should be controlled at 80-90 °C by stirring. Then by means of cooling, filtration and drying you can get the desired product. The equation is as follows: 6I₂ + 11KClO₃ + 3H₂O → 6KH(IO₃)₂ + 3Cl₂ + 5KCl. And it can be used as an intermediate for the synthesis of potassium iodooate. Moreover, it can be used as analysis reagent.
