A colloid is a ______ mixture and its components can be separated by the technique known as ______.

Colloids:

• Colloids are mixtures in which microscopically dispersed insoluble particles of one substance are suspended in another substance.
• The size of the suspended particles in a colloid can range from 1 to 1000 nanometers.
• Colloids are heterogeneous in nature.
• Colloids are separated through the centrifugation technique.

Heterogeneous mixtures

• Heterogenous mixtures in which all the components are completely mixed and all the particles can be seen under a microscope.
• Particles are distributed non-uniformly
• There are two or more phases.
• It can be separated out physically.

Centrifugation.

• The filtration technique cannot be utilized to separate such particles .such mixtures are separated by centrifugation.
• A centrifuge is a device that separates different components of a fluid using centrifugal force. This is accomplished by spinning the fluid at a high speed within a container separating different densities of fluids or liquids from solids.

Therefore, a colloid is a heterogeneous mixture and its components can be separated by the technique known as centrifugation.
