In addition to iron and aluminum in the cold oxidizing acid will passivate other will not passivate, heating will react back only these two metals, passivated metals are required to form a dense oxide film, to do this, the generated oxide must be dense, and the formation of ionic bonds or covalent bonds strong oxide; The valence of this metal is generally 3-4! Now you can determine which metals can be passivated.
< br >
Alkali metal and alkaline earth metal, the valence can not reach 3-4, certainly not passivation!
Passivation is the need to generate an oxide film that does not react with air, the more active metal, the formed oxide will have other reactions in the air, so it can not be.
