Polarization electrochemical tests indicate that chromium, Cr, corrodes actively

Question

Polarization electrochemical tests indicate that chromium, Cr, corrodes actively in de-aerated 1N H2SO4. Illustrate this corrosion situation on a schematic E vs log i diagram and write the appropriate anodic and cathodic reactions. Propose 2 ways or methods of reducing the corrosion of Cr in this acidic environment. Briefly explain why the methods would work and use the E vs log i diagram to provide additional graphical explanation. (Note that the environment cannot be changed to neutral or basic.)
