Aluminum oxide forms a tightly packed protective layer that does not admit water. Because iron(III) oxide is not tightly packed, it allows water to penetrate and attack the metal below.
Sodium oxide forms a tightly packed protective layer that does not admit water. Because iron(III) oxide is not tightly packed, it allows water to penetrate and attack the metal below.
Patrolium oxide forms a tightly packed protective layer that does not admit water. Because iron(III) oxide is not tightly packed, it allows water to penetrate and attack the metal below.
