Based on the data given below :
$\begin{array}{ll}\mathrm{E}_{\mathrm{Cr}_2 \mathrm{O}_7^{2-} / \mathrm{Cr}^{3+}}^{\circ}=1.33 \mathrm{~V} & \mathrm{E}_{\mathrm{C}_2 / \mathrm{Cl}^{(-)}}^{\circ}=1.36 \mathrm{~V} \\ \mathrm{E}_{\mathrm{MnO}_4^{-} / \mathrm{Mn}^{2+}}^{\circ}=1.51 \mathrm{~V} & \mathrm{E}_{\mathrm{Cr}^{3+} / \mathrm{Cr}}^{\circ}=-0.74 \mathrm{~V}\end{array}$
the strongest reducing agent is :
Select the correct option:
A
Cr
B
$\mathrm{Cl}^{-}$
C
$\mathrm{Mn}^{2+}$
D
$\mathrm{MnO}_{4}^{-}$
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
For strongest reducing agent
Reduction potential should be lowest
Hence Cr is the strongest reducing agent.
