Deviations from Raoult's Law in H₂O + D₂O Liquid Mixtures

Abstract

Deviations from Raoult's law in H₂O+D₂O liquid mixtures are calculated from vapour pressure isotope effects for HDO and D₂O by assuming that the equilibrium H₂O+ HDO+D₂O liquid mixtures are ideal solutions. The results are in good agreement with those obtained experimentally from liquid-mixture vapour pressure and boiling point measurements.
