Based on the data given below:
\(\mathrm{E}_{\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-} / \mathrm{Cr}^{3+}}^{0}=1.33 \mathrm{~V} \quad \mathrm{E}_{\mathrm{Cl}_{2} / \mathrm{Cl}^{(-)}}^{0}=1.36 \mathrm{~V}\)
\(\mathrm{E}_{\mathrm{MnO}_{4}^{-} / \mathrm{Mn}^{2+}}^{0}=1.51 \mathrm{~V} \quad \mathrm{E}_{\mathrm{Cr}^{3+} / \mathrm{Cr}}^{0}=-0.74 \mathrm{~V}\)
the strongest reducing agent is :
1
Mn2+
2
Cr
3
\(\mathrm{MnO}_{4}^{-}\)
4
Cl–
