An electrochemical cell is constructed by placing a strip of nickel metal in a solution that contains nickel(II) ions and a strip of copper metal in a solution that contains copper(II) ions. The two metal strips are connected by a conducting wire, and the solutions are connected via a salt bridge filled with sodium nitrate solution.

(a)    Sketch the cell (may be done in your written work). Label the anode and cathode, give the signs of the electrodes, and indicate the direction of electron and ion movement. (5 pts)

(a)    Write the oxidation half-reaction equation and the reduction half-reaction equation. Write the overall net ionic equation. (3 pts)

(b)    Calculate E° for the reaction that occurs in the cell.
