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.
Properties of colloids are as follows:
1.It seems as homogeneous but actually heterogeneous.
2.The dispersed phase particles size is 10 to the power minus 4 cm to 10 to the power minus 7 cm.
3.It may scatter the beam of light.
4.It's particle may not be separated or filtered ;only it may be separated by ultra filtration.
5.It's particle may not settle in the bottom of the vessel even it's keeping undisturbed for a long time.
