Question

Q3. differentiate between peptization and coagulation.

Answer 1

First of all peptisation is a method of formation of colloidal solution while coagulation is a method to destroy a colloidal solution

Peptisation:- It is the process of formation of colloidal solution in which a newly formed precipitation is converted into colloidal solution by adding suitable electrolyte having common ion

Coagulation:- as we know colloidal particle have charge on them which make them continuously move and they do not settle down. So to stop their motion a solution is added having opposite charge to that of colloidal particle. so they settle down .
