This communication presents the effect of five dissolved inorganic salts (sodium chloride, NaCl; calcium chloride, CaCl2; zinc chloride, ZnCl2; cadmium chloride, CdCl2; ammonium chloride, NH4Cl) on the enthalpy of mixing (HE) of ethyl acetate/benzene binary system at 303.15 K; enthalpy measurements were performed using an isothermal displacement calorimeter with vapor space. The excess enthalpy of mixing of this system is significantly reduced in the presence of NH4Cl and NaCl; however, changes in the excess enthalpy of mixing were insignificant in the presence of CaCl2, ZnCl2, and CdCl2. The experimental values of HE were fitted into the Redlich–Kister equation, and deviations from the ideal value and binary parameters were calculated. The importance of solute–solvent interactions was demonstrated from the decrease in the excess enthalpy of mixing in the negative direction with an increase in the NaCl concentration.
