Question
Consider the voltaic cell made from the following redox couples:
Sb2O5(s) / Sb2O3(s)
E°red =
+0.69 V
&
MnO4 (aq) / MnO42 (aq)
E°red = +0.58 V
a) Write the balanced half-reaction that occurs in the anode under basic conditions. (Use the 1/2
reaction method to balance.)
b) Write the balanced half-reaction that occurs in the cathode under basic conditions. (Use the 1/2
reaction method to balance.)
c) Write the balanced overall cell reaction.
d) Calculate the standard cell potential.
e) Calculate the cell potential at 25°C when the cathode and anode are at pH = 8.50 and the
[MnO4] = [Mn042] = 0.0025 M. (Hint: What concentrations can you find given pH?)
