Suppose a powerful battery is connected between a pair of inert graphite electrodes dipped into a pot of molten aluminum oxide (Al2O3) (see sketch at right). The battery makes a current of electrons flow in the directions shown by the arrows in the sketch. Note: Group 14 and Group 24 metals all melt at temperatures lower than their salts. Which electrode is the cathode? Write a balanced equation for the half-reaction that takes place at electrode A. Write a balanced equation for the overall reaction. A OB 0 0 0-0 la X G ? A H 7e- B
