Abstract:

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 Monitor. 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.

Key words: Mixed solvents, Benzoic acid, Chlorobenzoic acid, Ionization thermodynamics
