6L.3

Postby Skyllar Kuppinger 1F » Tue Feb 25, 2020 5:06 pm

In part D I just have no idea what's going on in this cell. Both the cathode and anode are exactly the same except there's an H+ on the left and an OH- on the right. What is being reduced?? What is being oxidized??? Why are there 3 diff species on each side instead of 2???

H20 is involved in both redox half reactions. If you look in the appendix, you would use O2 + 2 H2O + 4 e2 --> 4 OH2 and O2 + 4 H1+ + 4 e2 --> 2 H2O. Also, for cell diagrams, the left is always the anode (oxidized) while the right is always the cathode (reduced).
