    Silver is obtained from \[Na\,[Ag\,(C{{N}_{2}})]\] by  reaction with:

    A) Fe                                

    B) Na    

    C) Zn                                

    D) Au

    Correct Answer: C

    Solution :

    [c] Zn Metals are recovered from complexes by displacement method using a more electropositive zinc metal. \[2\,{{[Ag\,{{(CN)}_{2}}]}^{-}}-\left( aq. \right)\,\,+Zn\,(s)\] \[\to \,2A\,(s)\,+{{[Zn\,(CN){{L}_{4}}]}^{2-}}(aq.)\] Zinc acts as a reducing agent.
