The Effect of Chloride Ions on Some Radiation Chemical Reactions in Aqueous Solution

Abstract

Thymine and ethanol compete for OH free radicals. In the presence of sodium chloride in acid solution the OH. radical is converted to a different species which reacts preferentially with thymine. By varying theride ion concentration independently it is shown that the conversion depends on both quantities and follows apparent third-order kinetics with''a rate7. 6 X 109 liter2 mole-2 sec-1 for the reaction OH. + Cl- + H+[forward arrow] Cl. + H2O.
