Chapter 13, Problem 13.25PAE

Using values from the table of standard reduction potentials, calculate the cell potentials of the following cells.

(a) $\text{Ga}\left(\text{s}\right)|{\text{Ga}}^{\text{3+}}\left(\text{aq}\right)\Vert {\text{Ag}}^{\text{+}}\left(\text{aq}\right)|\text{Ag}\left(\text{s}\right)$

(b) $\text{Zn}\left(\text{s}\right)|{\text{Zn}}^{\text{2+}}\left(\text{aq}\right)\Vert {\text{Cr}}^{\text{3+}}\left(\text{aq}\right)|\text{Cr}\left(\text{s}\right)$

(c) $\text{Fe}\left(\text{s}\right),\text{FeS}\left(\text{s}\right)|{\text{S}}^{\text{2-}}\left(\text{aq}\right)\Vert {\text{Sn}}^{\text{2+}}\left(\text{aq}\right)|\text{Sn}\left(\text{s}\right)$
