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

  • Iron combines with oxygen to form rust
  • The oxidation process of iron is known as 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 […]
