    Complex salt can be made by the combination of \[{{[C{{o}^{III}}{{(N{{H}_{3}})}_{5}}Cl]}^{X}}\] with [RPMT 2000, AFMC 2002]

    A) \[PO_{4}^{3-}\]

    B) \[C{{l}^{-}}\]

    C) \[2C{{l}^{-}}\]

    D) \[2{{K}^{+}}\]

    Correct Answer: C

    Solution :

      \[{{[Co\,{{(N{{H}_{3}})}_{5}}Cl]}^{x}}+2C{{l}^{-}}\to [Co\,{{(N{{H}_{3}})}_{5}}Cl]\,C{{l}_{2}}\].
