Chloric Acid


HClO3, a strong monobasic acid, in which chlorine is in the + 5 oxidation state. Chloric acid, which has not been obtained in pure form, is rather stable in cold aqueous solutions at concentrations below 30 percent. More concentrated solutions decompose: 8HClO3 = 4HClO4 + 3O2 + 2Cl2 + 2H2O. Chloric acid is a strong oxidizing agent, and its oxidizing strength increases with increasing concentration and temperature. For example, filter paper ignites in a 40-percent solution of the acid. Chloric acid is obtained as a result of the decomposition of hypo-chlorous acid, in the electrolysis of chloride solutions, and, under laboratory conditions, in the reaction of barium chlorate with dilute sulfuric acid: Ba(ClO3)2 + H2SO4 = BaSO4 + 2HClO3.

Chlorate salts correspond to chloric acid; the most important are sodium chlorate, potassium chlorate, calcium chlorate, and magnesium chlorate.
