Vedclass · Answer

(C) Arsenious sulphide $(As_2S_3)$ sol is a negatively charged sol. 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 order of valency for the given cations is $Al^{+3} > Ba^{+2} > Na^{+}$. Therefore,the correct order of coagulation power is $Al^{+3} > Ba^{+2} > Na^{+}$.

The coagulation power of an electrolyte for arsenious sulphide sol decreases in the order:
