For the cell

Question:

For the cell $\mathrm{Zn}(\mathrm{s}) \mid \mathrm{Zn}^{2+}(\mathrm{aq}) \| \mathrm{M}^{\mathrm{x}+}$ (aq) $\mid \mathrm{M}(\mathrm{s})$, different half cells and their standard electrode potentials are given below :

If $\mathrm{E}_{\mathrm{Zn}^{2+} / \mathrm{Zn}}^{0}=-0.76 \mathrm{~V}$, which cathode will give a

mximum value of $E_{\text {cell }}^{\circ}$ per electron transferred?

  1. $\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}$

  2. $\mathrm{Ag}^{+} / \mathrm{Ag}$

  3. $\mathrm{Au}^{3+} / \mathrm{Au}$

  4. $\mathrm{Fe}^{2+} / \mathrm{Fe}$


Correct Option: , 2

Solution:

$\mathrm{Ag}^{+} / \mathrm{Ag}$
