Question

Pitting corrosion occurs due to formation of ________

1. glass 2. Rubber 3. Plastic 4. pits and holes

Answer 1

Answer:

Explanation:

4. pits and holes

Answer 2

Formation of holes causes pitting corrosion

• Corrosion is a process through which a metal gets weakened or destroyed due to its conversion to a more stable form like metal oxide, hydroxide, etc.
• Pitting corrosion is a class/type of corrosion in which metal destruction occurs due to the formation of small pits or holes on the surface.
• Pitting corrosion occurs due to electrochemical reactions that take place between extensively damaged metal coating (starts acting like a cathode) and the metal underneath (starts acting like an anode).

Thus, Pitting corrosion occurs due to the formation of (Option 4) pits and holes.
