Determine the corrosion current density An iron piece is immersed in a HCI acid solution with ferric chloride also existing in the solution. Use the Evan plot for this situation below, determine the corrosion current density of iron. 1 0.5 0.25 0 E in V (vs SHE) -0.25 -0.5 -0.75 -1.25 1E-10 2H+ +2e=H2 Fe2++e=Fe 1E-9 1E-8 Fe3+ +e=Fe2+ 1E-7 1E-6 i (A/cm2) 1E-S 1E-4 1E-3
