Subject Year Month, 58 Discuss the mechanism by which the potential of a platinum electrode becomes poised by immer- sion into a solution of Fe(II) and Fe(III) in 1 M HCl. Approximately how much charge is required to shift the electrode potential by 100 mV? Why does the potential become uncertain at low concentra- tions of Fe(II) and Fe(III), even if the ratio of their concentrations is held near unity? Does this ex- perimental fact reflect thermodynamic considerations? How well do your answers to these issues apply to the establishment of potential at an ion-selective electrode?
