Calculate the standard electrode potential of the copper electrode if the standard electrode potential of the zinc electrode is -0.76 V and the standard cell potential is 1.10 V for the cell reaction: Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s). Use the equation Eºcell=Eº cathode - Eº anode where Eºcell is the standard cell potential, Eºcathode is the standard potential for the reduction half-reaction, and Eºanode is the standard potential for the oxidation half-reaction.
