“…Table 4 shows the binary (ion−CH 3 OH) and triple (ion− ion−CH 3 OH, the ion−CH 3 The relatively large and negative values of the ion−alcohol binary interaction x AB (1,0) was interpreted as responsible for some association phenomenon between the Na + or Cl − ions and the CH 3 OH in these mixtures. 16,17 A galvanic cell containing an Na + -glass membrane and Ag/AgCl electrodes were also used for collecting the potentiometric experimental data at (298.15) K. The Pitzer ion-interaction parameters β (0) , β (1) , and C φ (not previously reported) for NaCl in different mass fractions x = 0.10, 0.20, 0.30, 0.40, and 0.50 of CH 3 OH in water at relatively high concentrations were determined, and the results were reported. The available literature data, specifically for the CH 3 OH mass fractions x = 0.10, 0.30, and 0.50 in H 2 O, are mainly limited up to the molality of 0.2 mol·kg −1 , in which the triple interaction Pitzer parameter C φ are neglected.…”
