What is coagulation ?

Text Solution

Verified by Experts

The stability of the lyophilic sols is due to the presence of Charge on the colloidal particles . If this charge is neutralised the particles will come nearer to each other to form aggregates (or coagulate) and settle down under the force of gravity. This process of settling down of colloidal particles is called coagulation (or) flocculation (or) precipitation.
