摘要：

Vapour-pressure lowerings of HO2CCH2C(OH)(CO2H)CH2CO2H(aq) (citric acid) solutions in the (0.51 to 7.65) mol.kg(-1) molality range and at five temperatures from 298.15 K to 318.15 K were determined by applying the isoteniscopic technique. From these results, the apparent osmotic coefficients of HO2CCH2C(OH)(CO2H)CH2CO2H(aq) and the osmotic and activity coefficients of unionized HO2CCH2C(OH)(CO2H)CH2CO2H(aq) were calculated.
