Evaluation of the stability constant of Cl2˙ in neutral aqueous solution

Abstract

The stability constant (K1) of Cl2˙ has been measured in neutral aqueous solution using pulse radiolysis to generate Cl˙ by reaction of SO4˙ with Cl. K1 is found to be (4.7 ± 0.4)× 103 dm3 mol–1, compared with the literature value of 1.9 × 105 dm3 mol–1. This low value of K1 makes it possible to measure the rates of reaction of Cl˙ using pulse radiolysis. The technique is exemplified for the reaction Cl˙+ HCO2 for which k=(1.3 ± 0.4)× 108 dm3 mol–1 s–1 has been obtained.
