Abstract

Vapour-pressure lowerings of HO₂CCH₂C(OH)(CO₂H)CH₂CO₂H_(aq)(citric acid) solutions in the (0.51 to 7.65) mol.kg^-1molality 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.
