6. Calculate [Pb)] when the Ecell is 0.98 at 25.0°C for Mnal Mn1.3M)1PbqPb).
Calculate Ecell for the following reaction and conditions: 0.50 M Br2 (aq), 0.10 M Pb+2 (aq), 0.30 M Br- (aq). Br2(aq) + Pb(s) --> Br- (aq) + Pb+2 (aq)……(unbalanced).
Calculate Ecell for Pb(s) | PbSO4(s) | Pb2+(aq) || Cu2+(aq) | Cu(s) the way it is written here given Cu2+(aq) + 2 e- → Cu(s) E° = +0.337 V PbSO4(s) + 2 e- → Pb(s) + SO42-(aq) E° = -0.356 V
Ksp =[ Pb^+2][I^-]^2
Ecell = 0 - 0.0592/2 log(Pb^2+ Anode/Pb^2+ Cathode)
Q3. Write and identify the oxidation and reduction half-reactions for the Pb-Pb concentration cell. Combine these to give the overall reaction equation. Use the Nernst equation to calculate [Pb2+] in the saturated Pbl2 solution and then calculate Ksp for Pbl2. Show all your work. (5.0)
