2) The size of particles of a colloid is too small to be individually seen by naked eyes..

What are two examples of colloids?

Mayonnaise and blood are both examples of colloids. A mixture in which very small particles of one substance are distributed evenly throughout another substance. The particles are generally larger than those in a solution, and smaller than those in a suspension. Paints, milk, and fog are colloids.

What are properties of colloid?

Physical Properties of Colloidal Solutions Stability: Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution. Filterability: Colloids require specialized filters known as ultrafilters for filtration.
