Chapter 18, Problem 18.48QE

The standard potential of the cell reaction

${\text{Ag}}^{+}\left(\text{aq}\right)+{\text{Eu}}^{2+}\left(\text{aq}\right)\to \text{Ag}\left(\text{s}\right)+{\text{Eu}}^{3+}\left(\text{aq}\right)$

is E° = +1.23 V. Use the tabulated standard potential of the silver half-reaction to find the standard reduction potential for the europium half-reaction.
