Types of Colloids

Colloid is a uniform dispersion of fine solid particles in a liquid medium. An emulsion is a uniform dispersion of one liquid in another liquid which are not miscible.

Classifying Colloids. A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids.

Gels are a colloid of a liquid in a solid. There are also colloids of solids in other solids, as in some types of glass. One type of colloid often encountered in cooking are hydrocolloids. These are gels (solid) or sols (liquid) made of particles dispersed in water. Gelatin is a sol when hot, and a gel when cooled.

A sol is a colloidal solution suspension of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall effect. Examples include blood, pigmented ink, cell fluids and paint.
