Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Intermolecular Forces03:13

Intermolecular Forces

71.5K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Electromotive Force

Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled  that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc  with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Scaling

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Intermolecular vs Intramolecular Forces03:00

Intermolecular vs Intramolecular Forces

97.4K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Intermolecular Forces in Solutions

39.7K
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,...

Area of Science:

  • Soft Matter Physics
  • Computational Fluid Dynamics
  • Colloid Science

Background:

  • Thermophoresis describes particle movement in response to temperature gradients.
  • Understanding colloidal thermophoresis is crucial for applications in separation and transport.
  • Mesoscale simulation methods are needed to bridge molecular and macroscopic scales.

Purpose of the Study:

  • To investigate the thermophoretic force on a stationary colloid within a temperature gradient.
  • To compare simulation results with theoretical predictions based on Onsager's reciprocal relations.
  • To explore the influence of hydrodynamic boundary conditions and fluid advection on colloidal thermophoresis.

Main Methods:

  • Multi-Particle Collision Dynamics (MPC) simulations were employed.
  • The thermophoretic force on a colloid was measured.
  • A dimensionless number was introduced to assess local thermodynamic equilibrium.

Main Results:

  • A good agreement was found between simulated thermophoretic forces and theoretical predictions.
  • The thermophoretic force magnitude was shown to depend on the colloidal surface's hydrodynamic boundary condition.
  • The study quantified the disturbance of the interfacial layer by fluid advection.

Conclusions:

  • Colloidal thermophoresis exhibits a significant hydrodynamic character.
  • Theoretical predictions remain valid even when uniform gradient assumptions are not strictly met.
  • The introduced dimensionless number helps evaluate local thermodynamic equilibrium in such systems.
