From the following select the one which is not an example of corrosion.
From the following select the one which is not an example of corrosion.
Rusting of iron object
Production of hydrogen by electrolysis of water
Tarnishing of silver
Development of green coating on copper and bronze ornaments
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 $\mathrm{H}_2$ by electrolysis of water is an example of electrolytic cell.
