Study on Thermodynamics of NaCl in Mixed Solution of Water and 1,2-Propanediol
WANG Wei-dong,LI Jin-yan(College of Chemistry and Environmental Engineering,Hubei Normal University,Huangshi,435002,China)
The activity coefficient of NaCl in mixed solution of water and 1,2-propanediol were measured using conductivity method,and the relationship between activity coefficient and concentration of mixed solution were discussed.The relative partial molar free energy of NaCl in mixed solution were calculated and change law of relative partial molar properties were discussed preliminarily.
