| Abstract: | he enthalpies of ionization of acetic, chloroacetic, bromoacetic ,iodoacetic ,propionic and n-butyric acids in water-ethanol mixtures were measured at 298. 15K with the LKB-2277BioActivity Monitor. The Gibbs free energies and entropies of ionization of these acids in solutionwere calculated. The effects of solvation and of substituting group on ionization were discussed. |
