what is the properties of colloids

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Brownian movement When a colloidal solution is viewed through a powerful microscope, the colloidal particles can be seen moving in a random zig-zag path. This zig-zag motion of colloidal particles is called Brownian movement. This random motion is due to c..

Colloids - It is well known, that solutions are homogenous systems while suspensions are heterogeneous systems, i.e., they consist of more than one phase. In between the extremes of suspensions and solutions lies the colloidal system. Colloids appear homogenous like a ..

A colloid is a solution in which the particle size ranges between 10 - 7 and 10 - 5 cm. For example, milk, blood, honey, smoke, ink, gum, starch solution et..

Property True Solutions Suspensions Colloidal Solutions Particle size Less than 10 - 7 cm Greater than 10 -5 c m Between 10 - 5 and 10 - 7 cm Visibility of particles Invisible to naked eye not visible under powerful microscope Easily visible Invisibl..

Colloids have uses in our daily life as well as in various industrial processes. Some of the applications where colloids are present are listed below. 1) Pharmaceutical industry makes use of colloidal solution preparation in many medicines. A wide variety of..

In this type of colloids the colloidal particles are aggregates of atoms or small molecules with molecular size less than one nanometer (1 nm). For e.g., gold sol consists of particles of various sizes which are clusters of several gold atoms. Similarly, sulphur sol consists of..

Colloids are characterized a) according to the state of the dispersed phase and the state of dispersion medium. b) nature of interaction between dispersed phase and dispersion medium. c) types of particles of the dispersed phas..
