Question: Voltaic cell is constructed from the following halfcells: a magnesium electrode in magnesium sulfate solution and a nickel electrode in nickel sulfate solution. The halfreactions

Voltaic cell is constructed from the following halfcells: a magnesium electrode in magnesium sulfate solution and a nickel electrode in nickel sulfate solution. The halfreactions are
Mg(s) → Mg2 + (aq) + 2e
Ni2 + (aq) + 2e → Ni(s)
Sketch the cell, labeling the anode and cathode (and the electrode reactions), and show the direction of electron flow and the movement of cations.
