40 Examples of Colloids
The colloids are homogeneous mixtures consisting of particles very small, the size of 1 micron (microscopic) which are in solid form (dispersed phase) and which spread in a liquid substance or another been called disperser, dispersing or continuous phase.
If we see the reflection of sunlight in a dimly lit place, we are likely to see a lot of dust particles floating in the air. This is an example of the colloid: the air is the disperser and the powder is in its dispersed phase.
Phases of a colloid
- The dispersed phase: corresponds to the particles in the solutions, and consists of molecules single or giant molecules such as starch. They can appear as independent particles or in groups.
- The dispersing phase: it is the substance in which the colloidal particles are distributed. This is the solvent in the solutions.
Many products that are used today are colloids: rubbers, plastics, paints, lacquers, varnishes; also some fruits that we eat and the clear soups that we prepare, among others.
