    The conductivity of dilute electrolyte solutions: Expanded lee and wheaton equation for symmetrical, unsymmetrical and mixed electrolytes (1993)
    Springer
    Journal of solution chemistry 22 (1993), S. 557-570 
    Details
    ISSN: 1572-8927
    Keywords: Electrolytic conductivity ; electrolyte mixtures ; unsymmetrical electrolytes ; lee-Wheaton equation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The conductivity equation of Lee and Wheaton is expanded in a power series in the ionic strength I. Different levels of approximation are analyzed and it is shown that for unsymmetrical electrolytes it is necessary to keep the terms I3/2lnI and I2 to maintain the performance of the full equation.

    Aqueous solutions of lithium hydroxide at various temperatures: Conductivity and activity coefficients (1979)
    Springer
    Journal of solution chemistry 8 (1979), S. 897-908 
    Details
    ISSN: 1572-8927
    Keywords: Electrolytic conductivity ; ion association ; mean activity coefficients ; alkali metal hydroxides
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The conductivity of LiOH aqueous solutions has been determined at 15, 25, and 45°C. The data analysis showed that LiOH is a slightly associated electrolyte, its association increasing with temperature. The association constant and distance parameter obtained from the conductivity data were successfully employed to calculate the activity coefficients of the solutions. The same procedure applied to very precise conductivity data for NaOH aqueous solutions enabled us to assess the reliability of this method of calculation of activity coefficients up to 0.1m. The alkali metal hydroxides show a reverse trend in the way their properties change with cationic radius, as is the case for the fluorides with which they are compared.

    Mobilities and ion-pairing in LiB(OH)4 and NaB(OH)4 aqueous solutions. A conductivity study (1980)
    Springer
    Journal of solution chemistry 9 (1980), S. 617-625 
    Details
    ISSN: 1572-8927
    Keywords: Electrolytic conductivity ; ion association ; mean activity coefficients ; ion-water interactions ; lithium borate ; sodium borate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The conductivities of aqueous solutions of sodium borate at 25°C and lithium borate at various temperatures are reported. The conductivity of the B(OH) 4 − ion is 35.3 ±0.2 S-cm2-mole−1 at 25°C. The electrolytes are both associated, the lithium salt being more associated than the sodium salt. The mobilities and association constants obtained from the conductivity data agree with a model recently proposed for the H2O−B(OH) 4 − interactions. A discrepancy in the reported thermodynamic behavior of NaB(OH)4 aqueous solutions has been resolved by means of the association constants obtained in the present study. Thus the usefulness of the conductivity measurements to determine excess chemical potentials of binary electrolytes in dilute solution is again shown.

    The conductivity of concentrated aqueous mixtures of NaCl and MgCl2 at 25°C (1989)
    Springer
    Journal of solution chemistry 18 (1989), S. 485-491 
    Details
    ISSN: 1572-8927
    Keywords: Electrolytic conductivity ; aqueous solutions ; mixed electrolytes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract As part of a cooperative study of the thermodynamic and transport properties of aqueous mixtures of NaCl and MgCl2 at 25°C, we report values of the molar conductivities of the mixed electrolyte in the concentration range 0.5 to 3.6 molar. It was found that the conductivities in the mixtures differ from those calculated assuming additivity of the conductivities of the component binary solutions by 4.65 S-cm2-mol−1 at constant total molarity and 0.50 S-cm2-mol−1 at total ionic strength.

    The conductivity of dilute aqueous solutions of magnesium chloride at 25°C (1988)
    Springer
    Journal of solution chemistry 17 (1988), S. 1059-1065 
    Details
    ISSN: 1572-8927
    Keywords: Electrolytic conductivity ; aqueous solutions ; ionic mobility ; magnesium chloride
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract There is a disagreement in the literature regarding the best value of Λo[1/2MgCl2]. For this reason, the conductivity of dilute aqueous MgCl2 solutions have been determined at 25°C. The new experimental data and those available in the literature have been analyzed with two theoretical treatments of electrolytic conductivity. On the basis of that analysis, the values 129.72±0.05 and 53.40±0.05 S-cm2-mol−1 for Λo[1/2MgCl2] and λo[1/2Mg2+], respectively, are recommended.
