    Which of the following complex will give white precipitate with \[BaC{{l}_{2}}\] \[(aq.)\] [JIPMER 1997]

    A) \[[Co{{(N{{H}_{3}})}_{4}}S{{O}_{4}}]N{{O}_{2}}\]

    B) \[[Cr{{\left( N{{H}_{3}} \right)}_{5}}S{{O}_{4}}]Cl\]

    C) \[[Cr{{(N{{H}_{3}})}_{5}}Cl]S{{O}_{4}}\]

    D) Both B and C

    Correct Answer: C

    Solution :

      \[[Cr{{(N{{H}_{3}})}_{5}}Cl]S{{O}_{4}}\to {{[Cr{{(N{{H}_{3}})}_{5}}Cl]}^{2+}}+SO_{4}^{2-}\] \[{{(Cr\,{{(N{{H}_{3}})}_{5}}Cl]}^{2+}}+SO_{4}^{2-}+BaC{{l}_{2}}\to \] \[[Cr\,{{(N{{H}_{3}})}_{5}}Cl]\,C{{l}_{2}}+BaS{{O}_{4}}+HCl\].
