Entropy and Solvation02:05

Entropy and Solvation

7.0K
The process of surrounding a solute with solvent is called solvation. It involves evenly distributing the solute within the solvent. The rule of thumb for determining a solvent for a given compound is that like dissolves like. A good solvent has molecular characteristics similar to those of the compound to be dissolved. For example, polar solutions dissolve polar solutes, and apolar solvents dissolve apolar solutes. A polar solvent is a solvent that has a high dielectric constant (ϵ...

Intermolecular Forces in Solutions

33.2K
The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
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,...

Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility

44.2K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

Solution Formation02:16

Solution Formation

31.4K
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.
This selective...

Aqueous Solutions and Heats of Hydration02:42

Aqueous Solutions and Heats of Hydration

14.6K
Water and other polar molecules are attracted to ions. The electrostatic attraction between an ion and a molecule with a dipole is called an ion-dipole attraction. These attractions play an important role in the dissolution of ionic compounds in water.
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...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

281
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

Summary

Molecular simulations reveal that hydrogen solubility in confined water within underground storage sites can be 25 times higher than in bulk water. This enhanced solubility and diffusion are crucial for designing effective underground hydrogen storage (UHS) systems.

Area of Science:

  • Geochemistry
  • Materials Science
  • Energy Storage

Background:

  • Underground hydrogen storage (UHS) is vital for a sustainable energy transformation, necessitating accurate modeling of hydrogen behavior in subsurface environments.
  • Understanding hydrogen's thermodynamic and transport properties within geological formations is critical for designing efficient and safe UHS sites.

Purpose of the Study:

  • To quantify the thermodynamic and transport properties of aqueous hydrogen (H2) confined within kaolinite slit pores using atomistic molecular dynamics (MD) simulations.
  • To investigate the influence of pore geometry and mineral surface interactions on hydrogen solubility and diffusion.

Main Methods:

  • Atomistic molecular dynamics (MD) simulations were employed to model aqueous H2 within slit-shaped kaolinite pores of 10 and 20 Å widths.
  • Analysis focused on hydration layer formation, H2 distribution, solubility, and diffusion coefficients.

Main Results:

  • Confined water forms distinct hydration layers, significantly increasing H2 solubility (up to ~25x bulk) near siloxane surfaces due to water density fluctuations.
  • A dense hydration layer on the gibbsite surface largely excluded H2.
  • Despite reduced water mobility, H2 diffusion increased with decreasing pore width, linked to water density fluctuations.

Conclusions:

  • Confinement effects in kaolinite pores dramatically alter hydrogen's solubility and transport properties compared to bulk conditions.
  • These findings provide crucial insights into H2 permeability relevant for the design and optimization of underground hydrogen storage facilities.
