“…In recent years, this drawback has been overcome thanks to the development and improvement of new ion-selective electrodes (ISE). Presently, these electrodes are not only valuable for analytical use, but also may be employed in determining thermodynamic and transport magnitudes [4][5][6]. The bi-ISE system employed in this study is formed of a glass-membrane electrode selective for Na + ions, and a liquid membrane electrode selective for BF À 4 ions.…”

“…The temperature was kept constant at 298.15 for all the studies. These studies were carried out using potentiometric techniques which have advanced markedly in recent decades due mainly to the development and improvement of new ion-selective electrodes (ISEs) [13][14][15][16][17][18][19][20][21]. Now, these electrodes are not only valuable for analytical use, but also may be employed in determining thermodynamic and transport magnitudes.…”

The mean activity coefficient of NaCl in NaCl− SrCl 2 −H 2 O was measured at 308 K by the electromotive force method. The total ion strength range of the mixed solution was 0.0100−1.0000 mol•kg −1 , and the ion intensity fraction of y b of SrCl 2 , i.e., y b = (0.8, 0.6, 0.4, 0.2, 0). A liquid-free electrochemical cell (Na-ISE | NaCl(m 1 ) SrCl 2 (m 2 )| Cl-ISE) was used to determine the electromotive force of a NaCl single salt and mixed solution. According to experimental data, the activity coefficient diagrams were drawn. The experimental results show that the measured activity coefficients are accurate and reliable, and the average activity coefficient of NaCl decreases with the increase of the ion strength of SrCl 2 . Using the measured average activity coefficient of NaCl, the parameters of the mixed ion action of the Pitzer equation θ Na + •Sr 2+ and φ Na + •Cl − •Sr 2+ are fitted. Furthermore, the Pitzer equation is used to calculate the average activity coefficents of SrCl 2 , the water activities a w , osmotic coefficients Φ, and Gibbs free energies G E of the mixed system.
