Vedclass · Answer

(A) According to the Hardy-Schulze rule,the coagulating power of an electrolyte depends on the valency of the active ion (the ion carrying a charge opposite to that of the colloidal particles).For a negatively charged clay sol,the coagulating power depends on the cation.The coagulating power increases with the increase in the valency of the cation $(Al^{3+} > Ca^{2+} > Na^+)$.Therefore,the electrolyte with the highest valency of the cation will require the minimum amount for precipitation.$AlCl_3$ provides $Al^{3+}$ ions,which have the highest valency among the given options.
