Chapter 19, Problem 19.43QP

A voltaic cell is constructed from the following half-cells: a chromium electrode in chromium(III) sulfate solution and a lead electrode in lead(II) sulfate solution. The half-reactions are

$\begin{array}{c}\text{Cr}(s)\stackrel{}{\to }{\text{Cr}}^{3-}(aq)+3{\text{e}}^{-}\\ {\text{Pb}}^{2+}(aq)+2{\text{e}}^{-}\stackrel{}{\to }\text{Pb}(s)\end{array}$

Sketch the cell, labeling the anode and cathode (and the electrode reactions), and show the direction of electron flow and the movement of cations.
