Abstract

The reaction between chlorite and iodide in acidic solution (0. 08 less than pH less than 3. 75) has been studied in a stirred-tank reactor at 25 degree C over a range of flow rates, pH, and input chlorite and iodide concentrations. The system is found to exhibit bistability and, at high left bracket ClO//2** minus right bracket and left bracket I** minus right bracket , sustained oscillations as well. The key reaction which gives rise to these phenomena is ClO//2** minus plus 4I** minus plus 4H** plus equals Cl** minus plus 2I//2 plus 2H//2O, which is autocatalytic in iodine and is inhibited by iodide. The existence of bistability and oscillations in this system with the ″cross-shaped phase diagram″ model of J. Boissonade and P. De Kepper.
