Ionic Mobilities at Infinite Dilution: Structural Aspects

Abstract

Empirical correlations between ionic mobilities and parameters characteristic of the solvent molecules motions for a variety of single ions and 1‐1 electrolytes at infinite dilution in 19 one‐component solvents and 8 aqueous‐nonaqueous mixed solvents are found, presented and discussed. The parameters are the self‐diffusion coefficient, the dipole relaxation time, the rotational correlation time of various NMR vectors, and the residence time of solvent molecules in the first ion solvation shell. The residual friction coefficients are considered in a more theoretical vein.

Effect of dielectric constant of medium on chemical speciation of L-histidine complexes of Co(II), Ni(II) and Cu(II)

“…The water-DMSO mixture influences microscopic dynamics of solvated ions [33,34] and dye molecules [35,36] so that these solutes exhibit a qualitatively different behavior compared to the behavior in other solvents. The variation of overall stability constant values or change in free energy with co-solvent content depends upon two factors, viz., electrostatic and nonelectrostatic.…”
