Hello everybody, this is probably a very novice question, but imagine anode and cathode, both made from copper immersed in CuSO4 aqueous solution (1M at standard temp and pressure + assuming electrodes are very near each other -> minimizing diffusion/migration resistance) and: Cu(2+) + 2e- -> Cu(s) = 0.337V (SHE) and Cu(s) <- Cu(2+) + 2e- = -0.337V (SHE) In this scenario would the cell voltage be 0V? In literature and articles Ecell is usually defined as Ecell = Eox + Ered. If this is correct, does the CuSO4 molar concentration affect Ecell if electrodes are very near each other? How does one determine activity coefficient in Nernst equation? Thanks!
