Which one of the following does not involve coagulation?
1 Formation of delta regions
2 Peptization
3 Treatment of drinking water by potash alum
4 Clotting of blood by the use of ferric chloride
Explanation:
The dispersion of a freshly precipitated material into colloidal solution by the action of an electrolyte solution is termed peptization. It involves the adsorption of suitable ions and the electrically charged particles then split from the precipitate as colloidal particles.

On which of the following properties does the coagulating power of anion depend?
1 Both magnitude and sign of the charge on the ion.
2 The sign of charge on the ion alone
3 Size of the ion alone
4 The magnitude of the charge on the ion alone
Explanation:
According to Hardy Schulze rule, the coagulating power of an ion depend on both magnitude and sign of the charge of the ion.
