    Alkali metal and ammonium chlorides in water + urea systems ΔG, ΔH, ΔS of transfer from water to mixtures containing up to 40 % urea
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (07), 1977) Pointud, Yvon; Juillard, Jean
    Enthalpies, Gibbs free energies and entropies of transfer from water to water + urea mixtures for LiCl, NaCl, KCl, RbCl, CsCl and NH4Cl are reported. Gibbs free energies are obtained using glass electrodes sensitive to alkali cations and enthalpies of transfer are calculated from calorimetric measurements of the enthalpies of solution. Data thus obtained are discussed in terms of the various models of the water + urea mixtures. It is suggested that the properties of solutes are mainly related to the properties of water in the same mixture.

    Solute-Solvent Interaction in Water+t-Butylalcohol Mixtures Part 9.—Enthalpies of Transfer for KBr, KI, HBr and HI1
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (12), 1977) Pointud, Yvon; Juillard, Jean
    Enthalpies of transfer of HI, HBr, KI and KBr from water to water + TBA mixtures, which have been obtained from calorimetric measurements, are reported. Gibbs free energies and entropies of transfer are calculated from previous data. The solvation of these electrolytes in water + TBA media is thus discussed in relation to the structure of the mixtures with special reference to the Atkinson's model of fluctuating cages.
