why is fe 2+ a better reducing agent then mn2+. ( I thought since mn2+ had a higher Eox it would be better)

I looked up
Fe^+2 ==> Fe^+3 + e. Loss of electrons is oxidation so Fe+2 is being oxidized; therefore it is the reducing agent.
Mn^+2 ==> Mn(IV) + 2e
Fe = -0.77
Mn = -1.24
Therefore, Fe is the more positive value so it's better.
