Pair Distribution Functions

An explicit water molecular dynamics (MD) simulation is presented of a solution modeling aliphatic 6,6-ionene oligocations mixed with low-molecular-weight electrolytes. In all cases, the co-ions were sodium cations and the counterions were fluoride, chloride, bromide, or iodide anions. The simple point charge/extended (SPC/E) model was used to describe water. The results of the simulation at T = 278 K (the data for 298 K were obtained earlier) and T = 318 K are presented in the form of pair distributions between various atoms and/or between ions in the system. We were interested in how temperature variation modifies the ion-specific effects, revealed by the various pair distribution functions (PDFs). The results were compared with previous calculations for the less hydrophobic 3,3-ionene solutions. Simulations of 6,6-ionene solutions containing mixtures of fluoride and iodide counter-ions at T = 298 K were also presented.

The Ideal

Differential capacitances are measured as a function of temperature at the ideal polarized Hg electrode in systems of mixed sodium halides at ionic strength J = 10−1 mol kg−1. A quasi-thermodynamic treatment is presented according to which excess entropies of adsorption in the inner layer are determined. The formation entropy of the inner layer and the water and ion molar entropies of adsorption are presented for a range of moderate and small ionic surface coverages.
