Conversion of collloidal state to suspenstion is called as coagulation

Lyophobic colloids easily undergo coagulation. By adding lyophilic colloids to lyophobic colloids, we can stabilise the lyophobic colloids. This is known as protection of colloids

Lyophobic colloids are unstable, they easily undergo coagulation, to stabilise them lyophilic colloids are added. These lyophilic colloids are called as protective colloids.
