Study of vapour pressure of lithium nitrate solutions in ethanol

Vapour pressure p of (LiNO3 + C2H5OH) solutions at T = (298.15 to 323.15) K were measured, osmotic, activity coefficients (ϕ, γ) and activity of solvent as have been evaluated. The experiments were carried out in the molality range m = (0.19125 to 2.21552) mol · kg−1. The Antoine equation was used for the empirical description of the experimental vapour pressure results and the (Pitzer + Mayorga) model with inclusion of Archer’s ionic strength dependence of the third virial coefficient for the calculated osmotic coefficients were used. The parameters of the Archer for the extended Pitzer model was used for the evaluation of activity coefficients.
