Which species is the strongest oxidizing agent based on the given standard electrode potentials?

\(E^{\ominus} values : \) \(\left(Fe\right)^{3 +} / \left(Fe\right)^{2 +} = + 0 . 77 V\)
\(I_{2} (s)/ I^{-} = + 0 . 54 V\)
\(\left(Cu\right)^{2 +} / Cu = + 0 . 34 V\)
\(\left(Ag\right)^{+} / Ag = +0 . 80 V\)


1. Fe3+
2. I2(s)
3. Cu2+
4. Ag+
