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.

Imagine that you are sailing on a yacht. The engine suddenly breaks down and you are stranded in the middle of the ocean. You call the Coast Guard on your radio, but cannot give them an exact location, because your GPS isn't working. Fortunately, you have a smoke flare, which you fire off. The dense colored smoke shows the Coast Guard where you are so that they can rescue you. In using the flare, you are taking advantage of a mixture called a colloid. A colloid is a heterogeneous mixture whose particle size is intermediate between those of a solution and a suspension. The dispersed particles are spread evenly throughout the dispersion medium , which can be a solid, liquid, or gas.

Some colloids are translucent because of the Tyndall effect , which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color.

IB Junior Intelligence Officer. Some hydrocolloids like starch and casein are useful foods as well as rheology modifiers, others have limited nutritive value, usually providing a source of fiber. Unstable colloidal suspensions of low-volume fraction form clustered liquid suspensions, wherein individual clusters of particles sediment if they are more dense than the suspension medium, or cream if they are less dense.
