Friday Section Test 2

For #6 on the test, why is the reducing agent O2?

The galvanic cell given is:

O3/O2, OH- and O3, H+/O2.

The reducing agent is O2 as seen in the half reaction: 2OH- +O2 --> 2e- + H2O +O3. One of the oxygens from the hydroxide goes from an oxidation state of 2+ to a neutral charge when forming ozone with the oxygen gas. thus it gives off 2e-s.

You can also think of the reducing agent as the one that is being oxidized.
