Which of the following is not true of the rusting of iron?

  • A Rusting is a reduction process
  • B Rusting of iron takes place in the presence of oxygen and moisture
  • C the rust formed is reddish brown
  • D the major constituent of rust is hydrated iron (lll) oxide
  • E rusting is similar to burning

The correct answer is A. Rusting is a reduction process

Rusting is actually an oxidation process.

It occurs when iron reacts with oxygen in the presence of water or moisture to form hydrated iron (III) oxide, commonly known as rust.

The iron is oxidized to iron (III) ions, which is an oxidation process, not a reduction process.
