Interactions in Aqueous Solutions of Hydrophilic Urea Derivatives and NaI at the Temperatures 293.15 and 303.15 K
Streszczenie
Measurements were made of the enthalpies of solution of NaI
in water and in aqueous 0.1, 0.7, 1.0 and 1.5 mol ureas kg H₂O
solutions of thiourea (TU) or hydroxyurea (HU) at the temperatures
293.15 and 303.15 K. Taking advantage of the standard
values of solution enthalpy of electrolytes in water and in
aqueous solutions of thiourea and hydroxyurea, the enthalpic
pair interaction coefficients of uruas molecule-averaged ion
were determined [l, 2],
