Notes:
It was established that chlorine reacts with both water and hydroxyl ions. At a short reaction time when the pH was less than 3 the reversible reaction of chlorine and water controlled the absorption rate. From pH 3 to 10.5 the forward reaction predominated and yielded an apparent first-order rate constant of 20.9 sec.-1 at 25°C. Between pH 10.5 and 12.5 the reaction of chlorine with hydroxyl ions occurred simultaneously with the chlorine-water reaction. Above pH 12.5 the second-order reaction between chlorine and hydroxyl ions became controlling and the reaction-rate constant was evaluated to be in the order of 106 liters/(mole)(sec.) at 25°C.These ionic reactions of chlorine were further interpreted through the collision and transition state theories. Certain important quantities with regard to the reaction characteristics were derived from the experimental data.
