Question

1. A galvanic cell is set up with a copper electrode in contact with 0.1M CuSO4(aq) and a lead electrode in contact with 0.1M Pb(NO3)2(aq), respectively, at 25ºC. The standard reduction potentials are: Pb2+ + 2 e- → Pb Eº= -0.13 V Cu2+ + 2 e- → Cu Eº= +0.34 V If H2SO4 is being added to the half-cell containing Pb(NO3)2 (thus forming a precipitate of PbSO4) until the final concentration of SO42- ions in solution is 2.4 x 10-1 M, what is the cell potential in Volt? Assume the volume of the the half-cell does not change upon addition of H2SO4. Ksp(PbSO4)=6.3 x 10-7.
