Abstract:
Through molecular dynamics simulations of imidazolium-based ionic liquid-water mixtures, it was found that the trace water leads to an anomalous non-monotonic change in the diffusion coefficients of ionic liquid, characterized by an initial decrease followed by an increase. Hydrogen bond analysis revealed that this unusual trend is governed by the weighted hydrogen bond lifetime, reflecting the stability of the hydrogen-bond network, rather than simply the number or energy of hydrogen bonds.

Aqueous Solutions and Heats of Hydration
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...
