Colloids are non-separating, non-settling mixtures.
While colloidal combinations are commonly thought to be homogeneous, microscopic examination reveals that they often have heterogeneous properties.
Every colloid has two components: The dispersed phase and the dispersing medium.
The dispersed phase of a colloid solution refers to the solute-like component (colloidal particles), whereas the dispersing medium refers to the solvent-like component.
Colloid particles are solids or liquids suspended in a medium. The size of these particles, which are larger than molecules, distinguishes a colloid from a solution.
A colloid, on the other hand, has smaller particles than a suspension.
Examples: Fog, whipped cream, milk.
Therefore, the two components of colloids are the dispersed phase and the dispersion medium.
