Balance the equation as a redox reaction in acidic solution.

Cu(s)+NO3^-1(aq)-->Cu^2+(aq)+NO(g)

    Tell us what method you are to use and what you don't understand about it.

  • Chemistry Redox Reaction - ,

    Cu(s)+NO3^-1(aq)-->Cu^2+(aq)+NO(g)
    Using the ion-electron method,
    1) The incomplete half reactions are:
    Cu(s) —> Cu^2+(aq)
    NO3^-(aq) —> NO(g)
    2) We use electrons, e^-, hydrogen ions, H+(aq), H2O, and OH^-(aq) to balance for electrical charge and for number of atoms.
    Cu(s) —> Cu^2+(aq) + 2e^-
    NO3^-(aq) + 4H^+(aq) + 3e^- —> NO(g) + 2H2O(L)
    3) We reconcile the number of electrons in the two balanced half reactions (Multiply the first one by 3, and the second one by 2):
    3Cu(s) —> 3Cu^2+(aq) + 6e^-
    2NO3^-(aq) + 8H^+(aq) + 6e^- —> 2NO(g) + 4H2O(L)
    4) We ADD the two half reactions:
    3Cu(s) + 2NO3^-(aq) + 8H^+(aq) + 6e^- —> 3Cu^2+(aq) + 6e^- + 2NO(g) + 4H2O(L)
    5) We simplify by doing the appropriate cancellations:
    [I leave that final step for you you to do]
