Activity Coefficients for NaCl in MeOH + H2O by Electromotive Force Measurements at 308.15 K and 318.15 K

Abstract

Electromotive force (emf) measurements of the cell Na ion-selective electrode (glass)|NaCl, MeOH + H2O|Cl ion-selective electrode (solid state) were made in methanol + water containing 0, 10, 30, 50, 70, and 90 mass % of methanol, at 308.15 K and 318.15 K, respectively. Using the Pitzer's equation calculations of standard cell potentials were made. The mean activity coefficients of NaCl were also derived.
