    Study Notes

    Corrosion of Metals

    • Oxygen is a substance that can accelerate the rusting of metals.

    Cause of Corrosion

    • The main cause of the corrosion process in metals is the reaction of the metal with oxygen in the presence of moisture.

    Reduction Reaction

    • The element consumed in the reduction reaction during the corrosion process is oxygen.

    Role of Electrons

    • Electrons play a crucial role in the corrosion process as they are transferred from the metal to the oxygen, resulting in the oxidation of the metal.

    Requirement for Corrosion

    • The requirement for corrosion reactions to occur is the presence of moisture and oxygen, which facilitates the reaction between the metal and oxygen.
