Imagine an electrochemical cell based on these two half reactions with electrolyte concentrations as given below:
Oxidation: Pb(s) → Pb2+(aq, 0.10 M) + 2 e–
Reduction: MnO4–(aq, 1.50 M) + 4 H+(aq, 2.0 M) + 3 e– → MnO2(s) + 2 H2O(l)
Calculate Ecell (assuming temperature is standard 25 °C).

For a silver-silver chloride electrode, the following potentials are observed:
E°cell = 0.222 V and E(saturated KCl) = 0.197 V
Use this information to find the [Cl–] (technically it’s the activity of Cl– that’s relevant here, but we’ll just call it “concentration” for simplicity) in saturated KCl.
