Current Question (ID: 8633)

Question:

\text{Given: } \text{E}^\circ_{\text{Cl}_2/\text{Cl}^-} = 1.36 \text{ V}, \text{E}^\circ_{\text{Cr}^{3+}/\text{Cr}} = -0.74 \text{ V} \text{E}^\circ_{\text{Cr}_2\text{O}_7^{2-}/\text{Cr}^{3+}} = 1.33 \text{ V}, \text{E}^\circ_{\text{MnO}_4^-/\text{Mn}^{2+}} = 1.51 \text{ V} \text{Among the following, the strongest reducing agent is:}

Options:

1. $\text{Mn}^{2+}$
2. $\text{Cr}^{3+}$
3. $\text{Cl}^-$
4. $\text{Cr}$

Solution:

\text{Hint: For strongest reducing agent } E^{\circ}_{\text{OP}} \text{ (oxidation potential) should be maximum.} \text{The oxidation potential value is as follows:} E^{\circ}_{\text{OP Cr}/\text{Cr}^{3+}} = 0.74 \text{ V} \text{Whereas} E^{\circ}_{\text{OP Mn}^{2+}/\text{MnO}_{4}^{-}} = -1.51 \text{ V} E^{\circ}_{\text{OP Cr}^{3+}/\text{Cr}_{2}\text{O}_{7}^{2-}} = -1.33 \text{ V} E^{\circ}_{\text{OP Cl}^{-}/\text{Cl}_{2}} = -1.36 \text{ V} \text{The strongest reducing agent has a maximum oxidation potential value.} \text{Hence, option fourth is the correct answer.}
