Half-cells were made from a nickel rod dipping in a nickel sulfate solution and a copper rod dipping in a copper sulfate solution. The half-reactions in a voltaic cell using these half-cells were
Cu2+(aq) + 2e→ Cu(s)
Ni(s) → Ni2+ (aq) + 2e
Sketch the cell and label the anode and cathode, showing the corresponding electrode reactions. Give the direction of electron flow and the movement of cations.
