OSORIO VIANA, Wilmar e GIRALDO OSORIO, Óscar Hernán. On the thermodynamics of electrolyte solutions. Rev.fac.ing.univ. Antioquia [online]. 2007, n.40, pp.7-21. ISSN 0120-6230.
The basic theoretical physical chemistry elements of electrolyte solutions are presented and subject to reflection, searching for a connection between the characteristic molecular aspects and the semi empirical thermodynamic models development, suitable for properties calculation. A general view of the historical development of models for electrolyte solutions is presented and the Debye-Hückel and NRTL-E models are adopted for describe qualitatively and quantitatively by virtual experimentation, the performance of solvent-inorganic electrolyte binary systems. The multielectrolyte solutions problem is addressed describing the fundamental characteristics of the unified approach model which is coupled to the NRTL-E model, allowing the treatment generalization without the inclusion of additional empirical parameters and with interesting contributions to theoretical understanding.
