    Under the influence of an electric field, the particles in a solution migrate towards cathode. The coagulation of the same solution is studied using\[NaCl\],\[N{{a}_{2}}S{{O}_{4}}\]and\[N{{a}_{3}}P{{O}_{4}}\]solution. Their coagulating values will be in maximum for

    A)  \[N{{a}_{3}}P{{O}_{4}}\]                             

    B)  \[NaCl\]

    C)  \[N{{a}_{3}}S{{O}_{4}}\]                             

    D)  None of these

    Correct Answer: B

    Solution :

     According to Hardy Schuiz's rule, an ion will be migrated towards cathode so greater in the valency of effective ion smaller will be its coagulating value, \[PO_{4}^{---},SO_{4}^{--},C{{l}^{-}}\]. So, \[NaCl\]will be answer.
