Chapter 19, Problem 19.139QP

The following two half-reactions arc involved in a voltaic cell. At standard conditions, what species is produced at each electrode?

$\begin{array}{ll}{\text{Ag}}^{+}+{\text{e}}^{-}\stackrel{}{\to }\text{Ag}\hfill & E°=0.80\text{V}\hfill \\ {\text{Ni}}^{2+}+2{\text{e}}^{-}\stackrel{}{\to }\text{Ni}\hfill & E°=-0.25\text{V}\hfill \end{array}$
