Based on the data given below: E°Cr2O7^2−/Cr3+ = 1.33V E°Cl2/Cl− = 1.36V E°MnO4−/Mn2+ = 1.51V E°Cr3+/Cr = −0.74V The strongest reducing agent is

1. Mn2+
2. Cr
3. MnO4−
4. Cl−

Correct answer: Cr

Solution

Cr is the strongest reducing agent because it has the most negative standard reduction potential among the options, indicating that it readily donates electrons and is more likely to be oxidized compared to the others.
