Oxidation of iron/Rusting

ZIMSEC O Level Combined Science Notes: Oxidation of iron/Rusting

  • Iron combines with oxygen to form rust
  • The oxidation process of iron is known asĀ rusting
  • Rust is a reddish-brown crust that forms on iron
  • It is iron oxide
  • \text{iron+oxygen}\rightarrow\text{iron oxide}
  • Most iron objects such as nails, paper clips, wires and iron coins rust when they are exposed to the atmosphere for an extended period of time
  • Rust is formed in the presence of moisture and air
  • Rust causes items to look unsightly
  • It also causes their eventual disintergration
  • It is thus important to prevent and reduce the effects of rusting

Preventing and reducing the effects of rusting

  • Painting
  • Using alloys
  • Galvanising
  • Electroplating
  • Oiling/Bluing
  • Using inhibitors
  • Controlling humidity
  • Using cathode protection
