Use the following information to answer questions 17 and 18. At one of the electrodes of an aluminium-air cell, moist air is bubbled through a sodium hydroxide solution. The half-reaction represented by the equation below occurs. Oz(g) + 2H,O(l) + 4e → 4OH (aq) i 17. The other half-reaction involving the aluminium electrode, Al(s), will occur at the and the type of cell is ii (3)0 The statement above is completed by the information in row Row A. B. C. D. i anode anode cathode cathode A. -2.06 V B. -1.26 V C. +1.26 V D. +2.06 V ii voltaic electrolytic voltaic electrolytic 18. If the half-reaction given above was assigned a standard reduction potential of zero, then would be the standard reduction potential of the half-reaction involving the aluminium electrode
