    In coagulating the colloidal solution of\[A{{s}_{2}}{{S}_{3}}\]which has the maximum coagulating value?

    A) \[NaCl\]                              

    B) \[KCl\]

    C)  \[BaC{{l}_{2}}\]                               

    D) \[AlC{{l}_{3}}\]

    Correct Answer: D

    Solution :

                    According to Hardy Schuize rule, the coagulating power of an electrolyte is directly proportional to the valency of active ions. Hence, to coagulate negative sol of\[A{{s}_{2}}{{S}_{3}}\]the coagulating power of different cations decrease as: \[A{{l}^{3+}}>B{{a}^{2+}}>N{{a}^{+}}\]
