Write the different equations for the lines that separate the areas

Write the different equations for the lines that separate the areas of corrosion, passivation and immunity using the Pourbaix Diagram.

HOMEWORK: Write the different equations for the lines that separate the areas of corrosion, passivation and immunity. - Al is very active - low reversible potential. - Al is protected by alumina passive layer. - Al is amphoteric - alumina (and thus Al ) is stable in mid pH region only.
