Question
![A galvanic cell is constructed in which the overall reac-
tion is
Pb(s) + 2 H;O* (aq) → Pb²+ (aq) + H2 (g) + 2 H20(e)
(a) Calculate AE° for this cell.
(b) Chloride ions are added until PbCl, precipitates at the
anode and [CI-] reaches 0.15 M. The cell potential is
then measured to be 0.22 V at pH = 0 and PH,
1.0 atm. Calculate [Pb2+] under these conditions.
(c) Calculate the solubility product constant Kp of PbCl2.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc86ae8b4-8072-44c1-858a-e689a302355a%2Fea415661-4610-4735-abab-cbb51b1db88e%2Fbbodbvk_processed.png&w=3840&q=75)
