Vedclass · Answer

(D) According to the Hardy-Schulze law, the coagulating power of an electrolyte depends on the valency of the active ion (the ion with a charge opposite to that of the colloidal particles).For a negatively charged $AgI$ sol, the coagulating power depends on the positive ions: $Na^{+}$, $Ba^{2+}$, and $Al^{3+}$.The coagulating power increases with the increase in the magnitude of the charge: $Na^{+} Since the amount of electrolyte required is inversely proportional to its coagulating power, the order of the amount required is: $NaNO_{3} > Ba(NO_{3})_{2} > Al(NO_{3})_{3}$.

The amount of electrolytes required to coagulate a given amount of $AgI$ colloidal solution ($-ve$ charge) will be in the order:
