easurements were performed to determine the solubilities of L-histidine
in aqueous solutions of various concentrations of chloride salts (NaCl and
KCl) by using a thermostatted reactor and gravimetric method from (293.15 to
323.15 K) under atmospheric pressure. The effect of inorganic salts on the
solubility of L-histidine was investigated and was found accordingly: sodium
chloride > potassium chloride. Results showed that the solubility in pure water
and in aqueous chloride solutions increased with increasing temperature. The
experimental data were well correlated by the semi-empirical equation. Using
the measured solubilities, the standard molar thermodynamic properties of
transfer of GA (∆

) from pure water to aqueous solutions of
the chloride salts were estimated
