Study Notes
Cell Reaction and Electrode Identification
- The overall cell reaction for the given cell is: Fe + 2Ag+ → Fe2+ + 2Ag
- The anode in the concentration cell Pt/H2 (8atm)/HCl(0.3M)/H2(2atm)/Pt is the electrode with 8atm H2
- The cathode in the given cell with the overall reaction Fe + 2Ag+ → Fe2+ + 2Ag is where the reduction reaction occurs: 2Ag+ → 2Ag
Cell Potential and Concentration
- The value of E0cell for the given cell is not specified, but it can be calculated using the standard electrode potentials of the involved half-reactions
- The potential of the concentration cell Pt/H2 (8atm)/HCl(0.3M)/H2(2atm)/Pt at 250C can be calculated using the Nernst equation, considering the concentration gradient of H2 and H+ ions
