Question

2) Consider a galvanic cell based upon the following line notation: Pb |Pb2 (1M)IIAg(1M)IAg Option 1. The standard cell potential, Eo, equals 0.67 v Option 2. The mass of the silver electrode is increasing Option 3. As the reaction proceeds, the concentration of the lead ions decreases. Option 4. Electrons are spontaneously produced in the silver half-cel. Option 5. Cations move to the lead half-cell. Option 6. The silver electrode is the anode. Option 7. The lead half-cell is the cathode. where Pb2+ + 2 e. Pb, E0m-0.13V Ag+ + e' Ag, E= 0.80 V Which of the following statements are true? Solve

Explanation / Answer

The E0Mn2+/Mn < E0Fe2+/Fe . so Mn system should undergo oxidation.

In brief the cell should written as :

Mn / Mn2+(aq) // Fe2+(aq) / Fe
