Vedclass · Answer

(C) According to the Hardy-Schulze rule,the coagulation power of an electrolyte depends on the valency of the active ion (the ion carrying a charge opposite to that of the colloidal particles).$As_2S_3$ sol is a negatively charged sol.Therefore,the coagulation power depends on the valency of the cation.The higher the valency of the cation,the greater is its coagulation power.Comparing the cations in the given electrolytes:$Na^+$ (from $NaCl$,valency $1$)$Mg^{2+}$ (from $MgCl_2$,valency $2$)$Al^{3+}$ (from $Al_2(SO_4)_3$,valency $3$)$NH_4^+$ (from $NH_4Cl$,valency $1$)Since $Al^{3+}$ has the highest valency $(3)$,$Al_2(SO_4)_3$ has the maximum coagulation power.

Which of the following electrolytes has the maximum coagulation power for $As_2S_3$ sol?
