Vedclass · Answer

(D) The $As_2S_3$ sol is a negatively charged colloidal solution. According to the Hardy-Schulze rule,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 sol,the coagulating power increases with the increase in the valency of the cation. The cations provided are $Ba^{2+}$,$K^{+}$,and $Al^{3+}$. Since $Al^{3+}$ has the highest valency $(+3)$,it will be the most effective coagulating agent for the negatively charged $As_2S_3$ sol.
