  1. Apply the idea of cell potential to predict the flow of electrons in chemical cells.
    1. Two solutions are connected to form an electrochemical cell:
      • Ag metal in AgNO3 solution
      • Sn metal in SnCl2 solution

        Draw a chemical cell showing the cathode, anode and the direction of electron flow in this electrochemical cell. Which metal is being oxidised and which is being reduced?
      • Two solutions are connected to form an electrochemical cell:
        • Ni metal in NiCl2 solution
        • Zn metal in Zn(NO3)2 solution

          Draw a chemical cell showing the cathode, anode and the direction of electron flow in this electrochemical cell.
