Water-diol mixtures as solvents of electrolytes. part 1. Enthalpies of solution of NaBPh4 and Ph4PCl in water with ethanediol-1,2,propanediol-1,2 and butanediol-1,2

Enthalpies and Entropies of Transfer of Electrolytes and Ions from Water to Mixed Aqueous Organic Solvents

“…Entropies of transfer may also be determined from nonisothermal cell emf (NICE) measurements. In the ∆ t H°) ∆ t G°+ T∆ t S°) ∆ t G°-T(∂∆ t G°/∂T) P (10) M|MX in w or s|X (I) 14) few instances where this approach has been employed, both polarography and potentiometry were used. [59][60][61] Initially, galvanic cell II, at 283 e T/K e 323, was used to obtain the dependence of the potential of the Ag|Ag + electrode on temperature where M stands for mol L -1 and Xfor CF 3 SO 3 -.…”

“…Application of the TPTB assumption using the Recommended values (Table 22) for NaCl (x EG e 0.4) and NaBPh 4 and the data of Emelin et al 182 for NaCl at higher x EG and of Pietrzak et al 10 for Ph 4 PCl enables calculation of values for ∆ t H°(ion, w f w + EG) for eight monovalent and four divalent cations and seven monovalent anions (Table 23).…”

Experimental study of the excess molar volume of ternary mixtures containing {water+(1,2-propanediol, or 1,3-propanediol, or 1,2-butanediol, or 1,3-butanediol, or 1,4-butanediol, or 2,3-butanediol)+electrolytes} at a temperature of 298.15K and atmospheric pressure

“…Experimental study of the enthalpic behavior in aqueous mixtures containing alkanediols due to presence of electrolytes were performed by Checoni and Francesconi [5], Taniewska-Osinska and Pietrzac [11,12] and Pietrzac et al [13]. However, studies involving the influence of an electrolyte on V E m of aqueous mixtures, specially containing alkanediols, are inexistent.…”

Enthalpic interaction coefficients of NaI–alkanediol pairs in methanol and in water

“…Systems containing an electrolyte and non-electrolyte in aqueous and N,N-dimethylformamide (DMF) solutions have been of interest to our laboratory for a long time [1][2][3][4][5][6][7][8]. In order to analyze intermolecular interactions in the systems under investigation the so-called enthalpic interaction coefficients model, derived from McMillan-Mayer's theory, was used [9].…”
