Proton dissociation constants (pKa) of a set of hydroxyl azo dyes in various organic solvent+ water mixtures have been determined. The results obtained were discussed in terms of the solvent characteristic. Effects of hydrogen-bonding interactions and solvent basicity on the ionization process have been also discussed. In a nutshell, the pKa values of the investigated compounds were found to be largely depending on both the ratio and the ...
