Corrosión

The video tutorial explains the process of iron oxidation, which requires both water and oxygen. It highlights that more reactive metals corrode faster, with aluminum being an exception. When aluminum corrodes, it forms a protective aluminum oxide layer that prevents further corrosion.

What two elements are necessary for iron oxidation to occur?

• Water and nitrogen

• Water and oxygen

• Oxygen and carbon dioxide

• Nitrogen and carbon dioxide

How does the reactivity of a metal influence its corrosion rate?

• More reactive metals corrode slower

• Less reactive metals corrode faster

• More reactive metals corrode faster

• Reactivity does not affect corrosion rate

Which metal forms a protective oxide layer when it corrodes?

• Zinc

• Iron

• Aluminum

• Copper

What is the role of aluminum oxide in the corrosion process?

• It has no effect on corrosion

• It causes aluminum to rust

• It prevents further corrosion

• It accelerates corrosion

Which of the following metals is an exception to the general rule of reactivity and corrosion?

• Gold

• Aluminum

• Copper

• Iron
