.what is colloid??? properties of colloid
Answers
Answer:
A colloid is a substance microscopically dispersed evenly throughout another substance.
• A colloid is a heterogeneous mixture.
• The size of particles of a colloid is too small to be individually seen by naked eyes.
• Colloids are big enough to scatter a beam of light passing through it and make its path visible.
• They do not settle down when left undisturbed, that is, a colloid is quite stable.
• They cannot be separated from the mixture by the process of filtration. But, a special technique of separation known as centrifugation can be used to separate the colloidal particles.
Explanation:
For example, milk is an emulsion, which is a colloid in which both parties are liquids.
Answer:
A colloid is a homogeneous non-crystalline mixture consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.They also show tyndall effect.
