Answer 2

Answer:

The assertion: Rusting of iron metal is the most common form of corrosion, which is correct.

The reason: The effect of rusting of iron can be reversed if they are left open in sunlight, which is incorrect.

Explanation:

Assertion: Rusting of iron metal is the most common form of corrosion.

• Rusting is an irreversible process.
• It takes place when an iron piece is left out in a humid environment. The iron reacts with water and oxygen present in the air.
• This reaction is called oxidation reaction or corrosion.
• Rusting can be prevented by painting the iron or storing it in oil.

Reason: The effect of rusting of iron can be reversed if they are left open in sunlight.

• The reason is incorrect as rusting is an irreversible process. Keeping a rusted iron under the sun will make no difference. It cannot reverse the rusting process.

Conclusion:

The reason is false while the assertion is correct.
