    Notes: Abstract Four diffusion coefficients for one composition of the system H2O-Bu4NBr-HBr were obtained at 25°C. The value of (D 12)v was negative and large as expected from the primary charge effect. However, the value of (D 21)v was also negative despite the fact that the primary charge effect predicts a positive value. This was interpreted to be a consequence of a large negative value for δ ln y2/δC1 which overshadows the primary charge effect.

    Diffusion studies of the systems water-succinic acid-urea and water-succinic acid at 25°C: The effect of complex formation on the diffusion coefficients of the ternary system (1974)
    Springer
    Journal of solution chemistry 3 (1974), S. 271-287 
    Details
    ISSN: 1572-8927
    Keywords: Isothermal diffusion ; binary system ; ternary system ; water ; succinic acid ; urea ; complex formation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Sets of four diffusion coefficients at 25°C were obtained for four compositions of the system H2O-succinic acid-urea. The binary diffusion coefficients of succinic acid in water were also obtained at 25°C. The effect of possible complex formation between solutes on the diffusion coefficients of the ternary system is discussed.

    Isothermal diffusion studies of the H2O-sucrose-KCl system at 25°C (1973)
    Springer
    Journal of solution chemistry 2 (1973), S. 477-488 
    Details
    ISSN: 1572-8927
    Keywords: Isothermal diffusion ; ternary system ; H2O-sucrose-KCl ; ionic mobility ; sucrose solution ; hydration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Diffusion coefficients were obtained for two compositions of the system H2O-sucrose-KCl at 25°C. These plus published diffusion coefficients of the same system at two other compositions led to the construction of three-dimensional surface diagrams. Using these diagrams, the diffusion coefficients of the ternary system were compared with those of binary systems of components. The main diffusion coefficient of KCl was estimated from the conductivity data of KCl in aqueous solution of sucrose, and the agreement of these with experimental values was found to be satisfactory. The possible cause for the appreciable size of the cross-term diffusion coefficients is discussed.

    Diffusion coefficients of the ternary system water-tetrabutylammonium bromide-potassium bromide as a function of tetrabutylammonium bromide concentration (1974)
    Springer
    Journal of solution chemistry 3 (1974), S. 149-159 
    Details
    ISSN: 1572-8927
    Keywords: Isothermal diffusion ; aqueous solution ; ternary system ; tetrabutylammonium bromide ; potassium bromide ; ionic transport coefficients ; water structure
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Sets of four diffusion coefficients were obtained for the water-tetrabutylammonium bromide-potassium bromide system at 25°C as a function of tetrabutylammonium bromide concentration with the mean concentration of potassiumbromide fixed at 0.1 mole-liter−1. The experiments were performed at tetrabutylammonium bromide concentrations of 0.075, 0.15, 0.3, and 0.45 mole-liter−1. The results are compared with the binary diffusion coefficients of these components and also with the calculated diffusion coefficients using the first approximation theory.
