Vedclass · Answer

(B) $Sb_2S_3$ sol is a negatively charged sol.According to the Hardy-Schulze rule, the greater the valency of the oppositely charged ion of the electrolyte added, the faster the coagulation.The principle is based on electrostatic forces of attraction.Greater the valency of the flocculating ion, greater is the coagulation power.Comparing the valency of the cations:$Al^{3+} > Ca^{2+} > Na^{+} = NH_4^{+}$Therefore, $Al_2(SO_4)_3$ is the most effective coagulating agent because it provides the $Al^{3+}$ ion with the highest valency.

The most effective coagulating agent among the options for $Sb_2S_3$ sol is
