A voltaic cell is constructed from the following half-cells: a magnesium electrode in magnesium sulfate solution and a nickel electrode in nickel sulfate solution. The half-reactions are Mg_(s) rightarrow Mg^2+_(aq) + 2e^- Ni^2+_(aq) + 2e^- rightarrow Ni_(s) Sketch the cell, labeling the anode and cathode (and the electrode reactions), label where oxidation and reduction take place, and show the direction of electron flow and the movement of cations.
