The enthalpies of ionization of benzoic, o-chloro-, m-chloro-, and p-chloro- benzoic acids in water-DMF mixtures were measured at 298.15K with an LKB-2277 Bioactivity Mointor. The corresponding entropies of ionization of the above acids were calculated.The effects caused by solvent and substitutent were explained by interaction between solute and solvent.
