摘要：
In this study solubility of DL-alanine is measured in aqueous solutions with various NaNO3 concentrations using the “formol titrimetry” method in the temperature range from 288.15 to 308.15 K. The standard transfer Gibbs energy and entropy have been evaluated for alanine. Chemical effects of the transfer Gibbs energy [ΔGi,ch0(i)], were obtained by subtracting theoretically computed ΔGt,cav0(i) and ΔGt,d-d0(i) from the total transfer free energy, ΔGt0(i). TΔSi,ch0(i) have been evaluated after elimination of cavity and dipole-dipole interaction effects from total transfer [TΔSt0(i)] entropy. Various solvents and thermodynamic parameters are presented in this manuscript. The data accumulated demonstrated that solubility was affected by the electrolyte.
