A mixture where tiny particles (1nm-0.5µm) are scattered within a different substance.

Colloids that readily disperse in a solvent, forming a stable mixture. They are 'solvent-loving'.

Colloids that resist dispersion in a solvent and are less stable. They are 'solvent-hating'.

A process where small particles are combined to form larger colloidal particles.

A process where large particles are broken down into smaller, colloidal particles.

The scattering of light by colloidal particles, making the beam visible. The light is scattered due to the difference in refractive index between the particles and the medium.

The random movement of colloidal particles in a fluid, caused by collisions with molecules of the dispersing medium.

The electrical potential difference between the surface of a colloidal particle and the bulk of the solution.

The electrical potential difference between the tightly-bound layers on a colloidal particle's surface and the bulk of the solution.

The aggregation of colloidal particles to form a loosely-bound network, typically caused by a decrease in zeta potential.

A mixture where particles are larger than 0.5µm and are not uniformly dispersed. Examples include emulsions and suspensions.

A law that describes the rate of settling of particles in a liquid, based on particle size, viscosity, and density differences.

A heterogeneous mixture of solid particles dispersed in a liquid, with particle sizes greater than 0.5µm.

A heterogeneous mixture of two or more immiscible liquids, where one liquid is dispersed in the other in the form of droplets.

A substance that stabilizes an emulsion by forming a film around the droplets to prevent coalescence.

The reversible separation of an emulsion into layers, where the dispersed phase rises or settles.

The irreversible separation of an emulsion into distinct phases, leading to total separation of the liquids.

The change in the dispersed phase and continuous phase of an emulsion, for example, switching from oil-in-water to water-in-oil.
