From the following select the one which is not an example of corrosion.

Options

  1. ARusting of iron object
  2. BProduction of hydrogen by electrolysis of water
  3. CTarnishing of silver
  4. DDevelopment of green coating on copper and bronze ornaments

Correct answer

B. Production of hydrogen by electrolysis of water

Step-by-step solution

Corrosion slowly coats the surfaces of metallic objects with oxides or other salts of the metal. The rusting of iron, tarnishing of silver, development of green coating on copper and bronze are some of the examples of corrosion. - Production of H ₂ by electrolysis of water is an example of electrolytic cell.
