“…The sodium ion-selective electrode was prepared in accordance with the general procedure of PVC membrane construction which has been reported in the previous works [17,18]. Also, the Ag-AgCl wire electrodes were prepared essentially as described elsewhere by electrolysis [19].…”

“…Hernandez-Luis et al measured the activity coefficients of NaF in N -methylformamide + water and NaCl in formamide + water and PEG 4000 + water mixtures. , Deyhimi et al determined the activity coefficient of NH 4 Cl and NaCl in some mixed solvents. The Pitzer ion-interaction model has been successfully used by these investigators. In addition, thermodynamic properties of (RbF + RbCl + H 2 O), (CsF + CsCl + H 2 O), (RbF + Rb 2 SO 4 + H 2 O), and (CsF + Cs 2 SO 4 + H 2 O) systems were studied by Huang and coworkers. , Hu et al reported the thermodynamic properties of (CsF + urea + H 2 O), (CsF + N -methylformamide + H 2 O), and (RbCl/CsCl + ethylene carbonate + H 2 O) ternary systems. , Moreover, the thermodynamic investigation of KCl in (glucose, formamide, diethanolamine, 1-PrOH, and proline + water) mixed solvent systems was done by our research group. The activity coefficients, osmotic coefficients, and excess Gibbs free energy for these electrolyte systems were determined by using ion-selective electrodes. Amides are well-studied solvents that are widely used as reagents and reaction media.…”

“…In this research, the thermodynamic properties of the (KCl + N , N -dimethylformamide + water) system were determined based on potentiometric technique. This work is an extension of our studies on the thermodynamic properties of alkali metal salts in mixed solvent systems. The cell potential measurements were performed by a galvanic cell of type: Ag|AgCl|KCl ( m ), DMF (wt %), H 2 O (1 – wt)%|K-ISE. This galvanic cell includes a potassium polymeric membrane (K-ISE) and Ag–AgCl electrodes that were made in our laboratory.…”

“…10−12 Furthermore, the presence of electrolyte solutions is encountered in separation processes for amino acids; thus, there is a need for a more profound understanding of the thermodynamic behavior of electrolyte + amino acid systems. 13 Ghalami-Choobar et al measured the mean activity coefficients for KCl in the proline + water system. 13 Zhuo et al determined the thermodynamic properties for CaCl 2 in (glycine, alanine, serine, or proline + water) mixtures at T = 298.15 K. 14,15 In our previous work, we obtained the mean activity coefficients of RbCl and CsCl in glycine + water mixtures and RbF and CsF in ethylene glycol + water.…”
