Chapter 19, Problem 38E

Use the Nernst equation and data from Appendix D to calculate $E_{\text{col}}$for each of the following cells

a. $\text{Mn}\left(\text{s}\right){\text{Mn}}^{\text{2+}}\left(0.40\text{M}\right)\left|\right|{\text{Cr}}^{2+}\left(0.25\text{M}\right)\text{Pt}\left(\text{s}\right)$

b. $Mg\left(s\right)\left(0.016\text{M}\right)\left|\right|{\left[\text{Al}{\left(\text{OH}\right)}_4\right]}^{-}\left(0.25\text{M}\right),{\text{OH}}^{-}\left(0.042\text{M}\right)\left|A\right|\left(\text{s}\right)$
