Chapter 8, Problem 8.33E

A concentration cell has different concentrations of the same ions, but because of the different concentrations there is a very small voltage between the cells. This effect is especially problematic for corrosion. Consider the following overall reaction, which is assumed to occur in the presence of metallic iron:

${\text{Fe}}^{\text{3+}}\left(0.08\text{M}\right)\to {\text{Fe}}^{\text{3+}}\left(0.001\text{M}\right)$

(a) What is $E°$?

(b) What is the expression for Q?

(c) What is $E$ for the concentration cell?

(d) Should concentration cells be considered another type of colligative property? Explain your answer.
