Solution
The correct option is B Hardy-Schulze rule
The quantity of the electrolyte which is required to coagulate a definite amount of a colloidal solution depends upon the valency of the coagulating ion (ion having a charge opposite to that of the colloidal particles). This observation of Hardy and Schulze is known as Hardy Schulze Law.
The main points of which may be stated as follows:
(i) The effective ions of the electrolyte in bringing about coagulation are those which carry a charge opposite to that of the colloidal particles. These ions are called coagulating ions or flocculating ions.
(ii) Greater is the valency of the coagulating or the flocculating ion, greater is its power to bring about coagulation.
