Vedclass · Answer

(D) According to the $Hardy-Schulze$ law,the coagulating power of an ion depends on the valency (magnitude of charge) of the active ion.Greater the valency of the flocculating ion added,the greater is its power to cause precipitation.Additionally,the ion must have a charge opposite to that of the colloidal particles to cause coagulation.Therefore,the coagulating power depends on both the magnitude and the sign of the charge.

The coagulating power of an ion for a given colloid depends on which of the following?
