Acid Disassociation Constant of The Carboxyl Radical

Authors: G. V. Buxton, R. M. Sellers Pulse radiolysis of aqueous solutions of formic acid and formate ion in the pH range 0-13 shows (i) that the absorption spectrum of the carboxyl radical is constant between pH 2.5 and 13, but decreases in intensity between pH 2.5 and 0 ; (ii)that the effect of ionic strength on the rate of…
