The rate of the disproportionation reaction of iodous acid at different acidity values in aqueous sulfuric acid solution
The dependence of disproportionation reaction kinetics of iodous acid, HOIO, in aqueous solutions of sulfuric acid on the solution acidity is examined. The rate constants of the disproportionation reaction are determined at temperatures of 18, 25 and 30 degrees C, based on kinetic data obtained under stationary conditions. The average value of the activation energy is determined to be 42 kJ/mol.
