    Notes: Abstract The freezing-point depressions of solutions of NaCl in normal and heavy water have been measured between 0.01 and 2m. Extrapolation of the isotope effect data to infinite dilution yields a new value for the heat of fusion of D2O at its melting point (−1507±3 cal-mole−1). The freezing-point data were employed to obtain osmotic coefficients at the feezing points of the solutions, which were corrected to rounded temperatures up to 40°C using the enthalpy data reported by Craft and Van Hook (previous paper). The data for H2O solution are in quantitative agreement with well-established results. Those for the D2O solvent establish the NaCl−D2O system as an isopiestic reference. In contrast to the statements of earlier authors, examination of the isotope-effect data reveals a $$\surd \overline m$$ dependence within experimental error.

    Thermodynamics of mixed electrolyte solutions. VI. An isopiestic study of a pseudo-ternary system: NaCl−KCl−MgCl2−H2O at 25°C (1975)
    Springer
    Journal of solution chemistry 4 (1975), S. 983-993 
    Details
    ISSN: 1572-8927
    Keywords: Osmotic coefficients ; activity coefficients ; excess free energy of mixing ; mixed salt solutions ; interaction coefficients ; NaCl ; KCl ; MgCl2

    Topics: Chemistry and Pharmacology
    Notes: Abstract Activity coefficients for magnesium chloride in the aqueous pseudo-ternary system sodium chloride-potassium chloride-magnesium chloride were derived from isopiestic measurements at 25°C. The isopiestic data were treated by both McKay-Perring and Scatchard methods, and results obtained agree fairly well over the ionic strength range of 1–6. At constant ionic strength, the activity coefficient of MgCl2 increased with addition of other salts. Interaction coefficients were obtained from Scatchard's and Friedman's formalisms. The excess free energy of mixing was calculated and compared with similar systems.

    Isotope effects in aqueous systems. V. Partial molal enthalpies of solution of NaCl−H2O−D2O and related systems (5 to 75°C)1 (1975)

    Notes: Abstract Solvent isotope effects on differential heats of solution of NaCl in HOH and DOD have been measured between 0.01 and 4m and from 5 to 40°C. These data are supplemented by integral heats of solution measured at 0.465m and from 5 to 75°C, and with heats of dilution over the same temperature range. The integral heat measurements include studies on otheralkali halides (KCl, NaI, NaBr), and the dilution measurements include some data for KCl. In the NaCl studies, particular attention was paid to the low-concentration region. Values of the partial molal enthalpiesL 1 adL 2 are derived for solution in both isotopic waters, and new values for the isotope effect on the standard enthalpy of solution ΔL 2 s = (ΔH 2 0 ) d←w as a function of temperature are reported. Comparisons are made with previous work where possible. In contrast to statements made by earlier authors, examination of the low-concentration data reveals a $$\surd \overline m$$ dependence within experimental error.
