Question
What is the coagulating power of an electrolyte? What is the cause of coagulation?
Solution
Answer:
Coagulating power of an electrolyte is the minimum amount of electrolyte in millimoles that must be added to one litre of a colloidal solution to bring about its coagulation.
Coagulation is caused by
(i) Electrophoresis,
(ii) Mutual precipitation by mixing oppositely charged sols in proper proportion.
