Applications
DescriptionChloric acid, HClO3, is an oxoacid of chloride, and the formal precursor of chlorate salts. It is a strong acid (pKa＝-1) and a strong oxidizing agent. It is stable in cold aqueous solution up to a concentration of approximately 30%, and solution of up to 40% can be prepared by careful evaporation under reduced pressure. Above these concentrations, and on warming, chloric acid solutions decompose to give a variety of products, for example: 8HClO3→4HClO4＋2H2O＋2Cl2＋3O2 Note that it disproportionates into perchloric acid in which the chlorine atom has a＋7 oxidation state and also the zero oxidation state of chlorine gas (an oxidation–reduction reaction). Thus, under the proper conditions, it can also be used to make perchloric acid. 3HClO3→HClO4＋H2O＋2ClO2
UsesOxidizing agent; with H2SO3 as catalyst in acrylonitrile polymerization.
