Vedclass · Answer

(B) According to the Hardy-Schulze rule,the coagulating power of an electrolyte depends on the valency of the active ion (the ion carrying a charge opposite to that of the colloidal particles). $As_2S_3$ is a negatively charged sol. Therefore,the coagulating power depends on the valency of the cation. Greater the valency of the cation,higher is the coagulating power and lower is the coagulation value. The valencies of the cations are: $Be^{2+}$ $(2)$,$Al^{3+}$ $(3)$,$K^+$ $(1)$,$Na^+$ $(1)$. Since $Al^{3+}$ has the highest valency $(3)$,it has the highest coagulating power and thus the lowest coagulation value. Therefore,$AlCl_3$ is the correct answer.

Which of the following has the lowest coagulation value for the coagulation of $As_2S_3$ colloidal solution?
