Chapter 17.4, Problem 17.6P

The standard potential for the following galvanic cell is 0.92 V:

     $\text{Al}\left(s\right)|{\text{Al}}^{\text{3+}}\left(aq\right)||{\text{Cr}}^{\text{3+}}\left(aq\right)|\text{Cr}\left(s\right)$

Look up the standard reduction potential for the Al³⁺/Al half-cell in Table 17.1, and calculate the standard reduction potential for the Cr³⁺/Cr half-cell.
