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.
