SUMMARY
The discussion centers on calculating the concentration ratio using Nernst's equation and understanding electrode potentials in electrochemical cells. Participants clarify that the total electrode potential is necessary to determine the Fe-ratio and emphasize that at equilibrium, while the cell potential (Ecell) is zero, the individual half-cell potentials are not. The conversation highlights the importance of correctly calculating cell potentials by simply subtracting the half-cell potentials without reversing the sign of one. This method simplifies the process and avoids common misconceptions.
