Coagulation Or Percipitation|Coagulation Of Iyophilic Sols

The correct order of the flocculating power in the coagulation of a positive sol is

What is meant by coagulation of a colloidal solution? Name any method by which coagulation of lyophobic sols can be carried out.

What is ment by coagulation of colloidal solution ? Describe briefly and three methods by which coagulation of lyophobic sols can be carried out.

What is coagulation? How is coagulation different from peptization?

Assertion :- Lyophilic sol coagulate by adding other solvent. Reason :- Lyophilic sol are stable due to hydration energy.

Read the given passage and answer the question that follow: Colloidal particles always carry an electric charge which may be either positive or negative. For example, when AgNO_3 solution is added to KI solution, a negatively charged colloidal sol is obtained. The presence of equal and similar charges on colloidal particles provide stability to the colloidal sol and if, somehow, charge is removed. coagulation of sol occurs. Lyophobic sols are readily coagulated as compared to lyophilic sols. Name one method by which coagulation of lyophobic sol can be carried out.
