MCQ
Based on the data given below:
$\begin{array}{l}
E_{Cr_2 O_7^{2-} / Cr^{3+}}^0=1.33 V \quad E_{C_2 / Cr^{(-1}}^0=1.36 V \\
E_{MnO_4^{-} / Mn^{2+}}^0=1.51 V \quad E_{Cr^{2+} / Cr}^0=-0.74 V
\end{array}
$
the strongest reducing agent is :
$\begin{array}{l}
E_{Cr_2 O_7^{2-} / Cr^{3+}}^0=1.33 V \quad E_{C_2 / Cr^{(-1}}^0=1.36 V \\
E_{MnO_4^{-} / Mn^{2+}}^0=1.51 V \quad E_{Cr^{2+} / Cr}^0=-0.74 V
\end{array}
$
the strongest reducing agent is :
- A$Mn ^{2+}$
- ✓Cr
- C$MnO _4^{-}$
- D$Cl ^{-}$
