SUMMARY
The strongest oxidizing agent among the half-reactions discussed is Cd2+, as confirmed by the standard reduction potentials. The half-reaction for fluorine, 2F- → F2 + 2e-, has a potential of -2.87 V and represents a reducing agent, not an oxidizing agent. The confusion arises from the need to interpret half-reactions correctly, where the oxidizing agent is identified by its ability to gain electrons, not by the reduction potential of its corresponding reducing agent. Therefore, the assertion that F- is the strongest oxidizing agent is incorrect.
