WebMay 1, 2016 · In the beginning, aluminium in its elemental state has the oxidation state 0. Apparently, that changes in the course of the reaction: A l ↽ − − ⇀ A l X 3 + + 3 e X − Where will the electron from a non-ionic aluminium atom go? Again, your observation is correct. If one species is oxidized, another one must get reduced. WebNov 9, 2009 · react with aluminum at the metal-oxide interface. At the same time, aluminum cations (positively charged ions) move outward from the valence band of the metal to react with water at the oxide-electrolyte interface. As a result, oxides are formed and continue to thicken at the two interfaces creating a dense layer of aluminum oxide …
