By using the gravimetric method, the equilibrium saturated solubility of L-serine and Lisoleucine in different aqueous mixtures of sodium nitrate (NaNO3) and potassium nitrate (KNO3) were determined at different temperatures ranging from 288.15 K to 313.15 K. The theoretical studies on the standard transfer Gibbs free energy were investigated with the help of experimental solubility data at five equidistant temperatures i.e. 288.15, 293.15, 298.15, 303.15 and 308.15 K. The molar volume, cavity forming enthalpy of transfer, cavity forming transfer Gibbs free energy, dipole-dipole interactions, etc., were also measured to explore complete thermodynamical aspects of these molecules in aqueous electrolytes. In addition the solutesolvent and solvent-solvent interactions in terms of chemical transfer Gibbs energies and transfer entropies for the present amino acids (AA'S) were obtained by deducting the cavity effects and dipole-dipole interaction effects from the total transfer Gibbs energy ( Gt0 (i ) ) and transfer entropies (T S t0 (i ) ). Finally the chemical stability of the amino acids in aqueous electrolytic solutions is explained by introducing the above mentioned thermodynamical parameters.
