Consider the standard reduction potentials:
E°(Cr3+/Cr) = −0.74 V; E°(MnO4−/Mn2+) = 1.51 V
E°(Cr2O7²−/Cr3+) = 1.33 V; E°(Cl2/Cl−) = 1.36 V
From the values above, which species is the most powerful oxidizing agent?

Question

Accepted Answer

MnO4−. MnO4− is the most powerful oxidizing agent because it has the highest standard reduction potential of 1.51 V, indicating it has a strong tendency to gain electrons and be reduced.
