Abstract

The excess Gibbs free energy changes on mixing aqueous solutions of tetrapropylammonium chloride and sodium chloride were determined at 298.15 K by the gravimetric isopiestic method. The experimental osmotic coefficients were treated by the Scatchard and Friedman procedures to yield the excess free energy of mixing ΔG^ex and the free energy interaction parameters g₀ and g₁. Results obtained are discussed in terms of self interaction of tetrapropylammonium cations as indicated by positive values of g₀.
