Question

Select the strongest reducing agent from the given electrode potential.

• A. $E_{Zn}^{\circ }/Zn$
• B. $E_{C{r}^{3+}/Cr}^{\circ }$
• C. $E_{H^{+}/H_2}^{\circ }$
• D. $E_{F{e}^{3+}/F{e}^{2+}}^{\circ }$

Answer 1

Answer: (A)

More negative the $E^{\circ }$, higher is the reducing power. So $Zn(s)$ is the strongest reducing agent among the given.
