Effect of ionic strength on acid-base equilibria of charged ions in highly basic media

Results of studies reported herein demonstrate that the overall reaction constant for the reaction of an organic acid, AH-, with OH- to yield reversibly B2- and water increase significantly with increased ionic strength. Some observations are made on the H- and H2-, scales which effectively extend the normal pH scale. The comments made are based on data from studies involving examination of deprotonation of carboxylated hydroxycyclohexadienyl radicals by ESR methods. The radicals of interest resulting from OH addition were produced by electron beam irradiation of N2O-saturated basic solutions of carboxylated benzene directly in the ESR cavity. 12 references, 1 figure
