The temperature-concentration dependences of the NaCl
activity coefficient in aqueous solutions of isopropanol (propanol-2) at temperatures of 298.15
and 323.15 K (solution ionic force, 0.01 to 3m; alcohol content, 10-60 wt %) were determined
through the electromotive force method with an ion-selective electrode. A Pitzer model was used
to mathematically describe the thermodynamic properties. The integral Gibbs energy of the
solution formation of the H2O-2-C3H7OH-NaCl ternary system was performed according to Darken's
method. The dissociation degree of salt in the investigated solutions was estimated using the
literature data on the association constant of NaCl in aqueous-isopropanol solution.
