Investigation of the Limits of the Linearized Poisson-Boltzmann Equation.
TL;DR: In this article , a comparison between a numerical solution of the Poisson-Boltzmann equation and the analytical solution of its linearized version through the Debye-Hückel equations considering both size-dissimilar and common ion diameters approaches is presented.
Journal ArticleDOI
The true Hückel equation for electrolyte solutions and its relation with the Born term
TL;DR: In this article , the authors presented Hückel's original derivation and considerations, verifying the approximations that were done in his paper, and compared these equations to the original Debye-Hueckel equation.

Generalized Debye–Hückel model for activity coefficients of electrolytes in water–methanol mixtures
TL;DR: In this article , a generalized Debye-Hückel model was proposed to calculate mean activity coefficients of electrolytes in water-methanol mixtures with arbitrary percentage of methanol from 0 to 100%.

Resurrection of Hückel’s idea: Decoupling ion-ion and ion-water terms in activity coefficients via the state-dependent dielectric constant
Mónika Valiskó,Dezső Boda +1 more
TL;DR: Vincze et al. as mentioned in this paper proposed a decoupled II+IW theory that splits the excess chemical potential into two terms corresponding to interactions between ions (II) and interactions between ion and water (IW), which can be computed independently with ϵ(c) being the only link between them.

Equilibrium Data and Correlation with Redefined NRTL Equation of Aqueous Two-phase Systems Based on 1,4-Bis-(2-hydroxyethyl)-piperazine and Na2SO4
TL;DR: In this article , the liquid-liquid phase equilibrium data of BHEP-Na2SO4 ATPS in 303.15 - 323.15 K were measured and correlated by NRTL equation with the redefined adjustable characteristic constant at different concentrations.

Local composition model for excess Gibbs energy of electrolyte systems. Part I: Single solvent, single completely dissociated electrolyte systems
TL;DR: In this paper, an electrolyte local composition model is developed for excess Gibbs energy, which is assumed to be the sum of two contributions, one resulting from long range electrostatic forces between ions and the other from short range forces between all the species.
Journal ArticleDOI
Thermodynamic properties of strong electrolytes in aqueous solutions
TL;DR: In this article, a generalized analytic correlation is presented for activity coefficient, enthalpy coefficient, and heat capacity of single and multicomponent strong aqueous solutions, where a good correlation for each salt to an ionic strength of six is obtained by assigning a single parameter "B" value to each salt.
Journal ArticleDOI
Mean spherical model for asymmetric electrolytes
TL;DR: In this paper, the mean spherical approximation for the primitive model of electrolytic solutions is solved for the most general case of an arbitrary charge and size, and the excess thermodynamic properties are scaled to the charge and the size by means of a rational expression involving a single parameter.
