Problem- You will construct several cells where both compartments contain a copper electrode and copper (II) solution. What cell potential (E0cell) would be expected for a cell comprised only of copper? What drives the movement of electrons from the anode to the cathode? Under what conditions will the cell stop?
The Voltaic cell is composed of Cu in 0.1 M Cu(NO3)2 and Cu in 1.0 M Cu(NO3)2
