A. Apelblat et al., THE VAPOR-PRESSURE OF WATER OVER SATURATED AQUEOUS-SOLUTIONS OF MALIC, TARTARIC, AND CITRIC ACIDS, AT TEMPERATURES FROM 288-K TO 323-K, Journal of Chemical Thermodynamics, 27(1), 1995, pp. 35-41
Vapour pressures of saturated aqueous solutions of DL-malic acid, L(+)
-tartaric acid, and citric acid were measured in the temperature range
288 K to 323 K, applying the isoteniscope technique. The water activi
ties, osmotic coefficients, and molar enthalpies of vaporization and o
f solution at saturation were evaluated from the measured vapour press
ures.
