|
|
It is of very less amount in respect of solvent
|
Explanation:
Detailed explanation-1: -The particles in a colloid do not settle down when left undisturbed due to their continuous zig-zag motion and are able to resisit the gravitational force. This makes colloids extremely stable.
Detailed explanation-2: -A phenomenon known as Brownian motion keeps the particles suspended in the solvent. Brownian motion is the constant bombardment of the colloid particles by the solvent molecules. This action prevents the colloid particles from settling out of the solvent.
