Given the following standard reduction potentials in acid solution



write the formula of the weakest reducing agent.

I don't see a reaction.

O2 + 4H+ + 4e- => 2H2O Eo= +1.23 V

Sn4+ + 2e- => Sn2+ Eo= +0.13 V
Zn2+ + 2e- => Zn(s) Eo= -0.76 V
I apologize for not checking my question after posting.

Zn ==> Zn^2+ + 2e is the strongest reducing agent (easiest to oxidize).

2H2O ==> O2 + 4e + 4H^+ is the weakest reducing agent, hardest to oxidize.

To determine the formula of the weakest reducing agent, we need to examine the given standard reduction potentials in acid solution.

However, you have not provided any standard reduction potentials for us to analyze. Please provide the necessary data for us to proceed and determine the formula of the weakest reducing agent.
