Heya friend,

Colloids are hetrogeneous Mixtures in which the size of solute particles is intermediate between particles of solution and of suspension.

Properties of colloids are as mentioned below-

•They are hetrogeneous Mixtures but sometimes they seems to be homogeneous.

•Size of the particles are between 1nm and 100nm.

•They are quite stable but sometimes they can settle down when kept un-disturbed for long.

•Particles are big enough to scatter beam of light which becomes visible when it passes through it. The best Tyndall effect is showed in it.

•When seen under the microscope, the particles become visible and they show Brownian movement.

•Particles aren't big enough to be filtered by ordinary filter paper. A special technique called 'Centrifugation' is used for separating them.

•They are generally opaque.


Hope it helps....^^

A colloid or a colloidal solution is a heterogeneous mixture in which one substance is displaced as very fine particles having size in the range of 1 to 100 nm , in a continuous medium for another substances.

They are heterogeneous mixture .

They can pass through filter paper .

They show Tyndall effect.

Example - Fog , cloud , milk etc.
