Colloid kya hai

Key Points. Additional Information. Last updated on May 8,

A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid , [1] while others extend the definition to include substances like aerosols and gels. 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 colloid has a dispersed phase the suspended particles and a continuous phase the medium of suspension. The dispersed phase particles have a diameter of approximately 1 nanometre to 1 micrometre.

In chemistry, a colloid is a mixture of tiny particles that are dispersed in another medium. In contrast, particles in a solution are smaller than this size, while particles in a suspension are larger. As in a solution, the particles in a colloid do not separate upon standing. The particles in a colloid are called the dispersed phase , which is spread throughout the dispersion medium. 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.

The dense colored smoke shows the Coast Guard where you are so that they can rescue you.
