Chapter 19, Problem 19.44QP

Half-cells were made from a nickel rod dipping in a nickel sulfate solution and a silver rod dipping in a silver nitrate solution. The half-reactions in a voltaic cell using these half-cells were

$\begin{array}{l}{\text{Ag}}^{+}(aq)+{\text{e}}^{-}\stackrel{}{\to }\text{Ag}(s)\\ \text{Ni}(s)\stackrel{}{\to }{\text{Ni}}^{2+}(aq)+2{\text{e}}^{-}\end{array}$

Sketch the cell and label the anode and cathode, showing the corresponding electrode reactions. Give the direction of electron flow and the movement of cations.
