Scavenging of and OH radicals in concentrated HCl and NaCl aqueous solutions

In neutral and acidic aqueous solutions containing 2 mol L−1 of Cl−, the decay of the solvated electron and the formation of ClOH− and Cl 2 - were studied by picosecond pulse radiolysis experiment. The rate constant for the reaction of e s − and H3O+ is 1.3 × 1010 L mol−1 s−1. The yield of the OH radical at 100 ps is estimated to be 5.0 × 10−7 mol J−1.
