Chapter 11, Problem 65E

Consider the concentration cell shown below. Calculatethe cell potential at 25°C when the concentration of ${\text{Ni}}^{\text{2+}}$ in the compartment on the right has each of thefollowing values.

a. 1.0 M   d. $\text{4}{\text{.0×10}}^{\text{-5}}M$
b. 2.0 M   e. Calculate the potential when both
c. 0.10 M   solutions are 2.5 M in ${\text{Ni}}^{\text{2+}}$ .
For each case, identify the cathode, the anode, and thedirection in which electrons flow.
