Abstract
Vapour-pressure lowerings of HO2CCH2C(OH)(CO2H)CH2CO2H(aq) (citric aci d) solutions in the (0.51 to 7.65) mol.kg(-1) molality range and at fi ve 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 acti vity coefficients of unionized HO2CCH2C(OH)(CO2H)CH2CO2H(aq) were calc ulated.
