What are the different types of colloidal solution?

Colloidal solution is a mixture in which very small particles of one substance are distributed evenly throughout another substance.

Colloidal Solutions can be mainly classified into:

Foam:

Foam in this setting is created by ensnaring a gas in a liquid. The substance being dispersed would be the gas, triggering the fluid to become frothy and foamy. Example : shaving cream.

Emulsion:

An emulsion is a combination of liquids; it’s basically when one liquid is consistently dispersed all through another liquid. Examples of this would be mayonnaise or milk.

Sol:

The third form is called a sol, which is when a solid is evenly dispersed throughout a fluid. Examples of sol include paint, blood and silver aquasol.

Aerosol:

It consists of a minute liquid or solid particles in a gas. Example: Fog, Insecticide sprays
