Solvation Thermodynamics of DL-Phenylalanine in Aqueous NaNO3 Solution at 298.15 K

详细

By “formol titrimetry” method solubilities of DL-phenylalanine (PA) in aqueous NaNO₃ solution were measured at 298.15 K. The standard Gibbs energy of PA in aqueous and aqueous NaNO₃ solution and also transfer free energy of PA was evaluated. The thermodynamic parameters: molar volume, densities, dipole moment and solvent diameter of aqueous solution of NaNO₃ have also been reported. Electrolyte effects on the solubility and relative stability of PA is guided by different types of interactions which are explained in this manuscript.
