Colloids are either colored or translucent due to light reflecting on the particles within them. Some examples of colloids include pumice, gelatin, smoke, dust and milk of magnesia. The term colloidal suspension is referring to a substance that has a solid permanently suspended in a liquid.
Colloidal suspension definition, See under suspension(def 6). See more.
Colloids can be distinguished from solutions using the Tyndall effect. A beam of light passing through a true solution, such as air, is not visible. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible.
In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size).
A colloidal suspension is a mixture of usually two materials where one is dispersed in the other at a microscopic level, but not chemically bonded to it. Liquids, solids, and gasses can all be part of a colloidal suspension with the exception that one gas cannot be colloidally suspended in another gas.

An example of a simple suspension would be flour in water, or sand in water. Colloids. A colloid is a type of mixture intermediate between a homogeneous mixture (also called a solution) and a heterogeneous mixture with properties also intermediate between the two. The particles in a colloid can be solid, liquid or bubbles of gas.
Colloids and suspensions are different from solution, in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed. A suspension of liquid droplets or fine solid particles in a gas is called an aerosol.
A colloidal solution, sometimes known as a colloidal suspension, is a solution in which a material is evenly suspended in a liquid. In other words, a colloid is a microscopically small substance that is equally dispersed throughout another material.
