What is the corrosion current density of a piece of iron immersed in a 0.5 M aqueous solution of NaCl at 25°C? The measured open circuit potential of the electrode is -0.55 V vs. a saturated calomel electrode (SCE) and the Tafel slopes for the anodic and cathodic reactions are 60 mV/decade and 100 mV/decade, respectively. The area of the electrode is 2 cm2.
