$AlCl_3$

Vedclass · Answer

(A) According to the Hardy-Schulze rule,the coagulating power of an electrolyte increases with the increase in the magnitude of the charge on the ion opposite to that of the colloidal sol.Since $As_2S_3$ sol is negatively charged,it requires a positively charged ion for coagulation.The coagulating power follows the order: $Al^{3+} > Ca^{2+} > Na^+$.Therefore,$AlCl_3$ is the most effective coagulating agent among the given options because it provides $Al^{3+}$ ions.

If $As_2S_3$ sol is negatively charged,which of the following will be most effective in causing its coagulation?
