Question

Consider a galvanic cell consisting of the Pb2+ (1M)/Pb and the Cl2 (1atm)/Cl- (1M) redox couples.
A) Which redox couple undergoes reduction?
B) Write an equation for the reaction that occurs at the anode and the cathode.
C) Write the equation for the overall cell reaction.
D) What is the standard cell potential, E cell, for the galvanic cell?

Explanation / Answer

a) redox couple undergoing reduction is Cl2/Cl- b) equation at cathode : Cl2 + 2e- ---------> 2Cl- anode: Pb ---------> Pb2+ + 2e- c) overall reaction: Pb + Cl2 ---------> Pb2+ + 2Cl- d) cell potential = (reduction potential of cathode)-(reduction potential of anode) = 1.36-(-0.13) = 1.49 V
