Examples of Colloids- Colloids refer to dispersions of small particles usually with linear dimensions from around 1 nm to 10 micrometers. It is regarded as an intermediate state between true solution and suspension. Examples of colloids solutions are Gel, Sol, Foam, Emulsion, Aerosol etc.

27 Σεπ 2022 · Colloids are classified as foams, aerosols, emulsions, gels, or sols, depending on the nature of the dispersed phase and dispersion medium. Familiar examples of colloids include mayonnaise, milk, fog, smoke, and gelatin. A gel is a colloid of solid particles in a liquid medium.
The table below lists a few examples of colloids. [1,3,6] Preparations. Colloids are created through various techniques, two prominent ones being the condensation method and the dispersion method. [2,6] Condensation Method. The condensation method initiates particle growth from smaller entities.
Colloid is a term that has come to encompass solid particles suspended in a liquid (a colloidal dispersion), microscopic droplets in a liquid (an emulsion), or either solid or liquid phases suspended in a gas (an aerosol).
Learning Objectives. By the end of this section, you will be able to: Describe the composition and properties of colloidal dispersions. List and explain several technological applications of colloids.
In this chapter, we will consider the nature of solutions, and examine factors that determine whether a solution will form and what properties it may have. In addition, we will discuss colloids—systems that resemble solutions but consist of dispersions of particles somewhat larger than ordinary molecules or ions.
Examples. Continuous phase is often water. Wide range of sizes: bovine serum albumin: 3 nm. cells: tens of microns. Classify colloids as hydrophobic (e.g., carbon black) or hydrophilic (e.g., red blood cell). Stability of colloid: essential part of its function. whether or not it will coagulate.
