    When copper turnings are added to silver nitrate solution, a blue coloured solution is formed after some time. It is because, copper              [CPMT 1974, 79; DPMT 2000]

    A)                 Displaces silver from the solution

    B)                 Forms a blue coloured complex with \[AgN{{O}_{3}}\]

    C)                 Is oxidised to \[C{{u}^{2+}}\]

    D)                 Is reduced to \[C{{u}^{2+}}\]

    Correct Answer: C

    Solution :

              Cu is above of Ag in electrochemical series and thus \[Cu+2A{{g}^{+}}\to C{{u}^{2+}}+2Ag\] reaction occurs.
