Using the following reduction half-reactions:
𝐴l3+(𝑎q) + 3𝑒- →
𝐴l(𝑠) 𝐸°𝑟ed = −1.662
𝐶u2+ + 2𝑒- →
𝐶u(𝑠) 𝐸°𝑟ed =
0.342
a. Calculate the Standard Cell Potential for the reaction:
3𝐶u2+(𝑎q) + 2𝐴l(𝑠) → 3𝐶u(𝑠) +
2𝐴l3+(𝑎q)
b. Is this an example of a voltaic or electrolytic cell?
c. Calculate the cell potential at 25 °C when [Cu2+] = 1.5 M and
[Al3+] = 0.0015 M.
d. Over time, the measured cell potential will slowly decrease.
Please explain why.
