Colloidal solutions are mixtures in which the particle size is between 1-1000nm such that they can pass through filter paper but not animal or plant membranes.  These particles also don’t settle upon standing for sometime.

They involve 2 substances called the dispersed phase and the dispersed medium

The dispersed phase- The substance that is dispersed in another medium to form a colloid. Usually lesser in quantity

Dispersed medium- The substance inside which the dispersed phase is dispersed
