The stoichiometric dissociation constants (pK) of gallic acid were determined in water and several mixed solvents comprising 10–90% (v/v) acetonitrile in water at a temperature of 24.0±0.5°C and an ionic strength of 0.10moldm −3 KCl medium. In this study, the protonation equilibrium values were calculated from potentiometric measurements and the influence of organic solvent composition on...
