Using the following reduction half-reactions:
π΄l3+(πq) + 3π- β
π΄l(π ) πΈΒ°πed = β1.662
πΆu2+ + 2π- β
πΆu(π ) πΈΒ°πed =
0.342
a. Calculate the Standard Cell Potential for the reaction:
3πΆu2+(πq) + 2π΄l(π ) β 3πΆu(π ) +
2π΄l3+(πq)
b. Is this an example of a voltaic or electrolytic cell?
c. Calculate the cell potential at 25 Β°C when [Cu2+] = 1.5 M and
[Al3+] = 0.0015 M.
d. Over time, the measured cell potential will slowly decrease.
Please explain why.
