Which of the following statements is not correct about rusting of iron?
- Coating of iron surface by tin prevents rusting, even if the tin coating is peeling off.
- When pH lies above 9 or 10, rusting of iron does not take place.
- Dissolved acidic oxides SO2, NO2Rusting of iron is envisaged as setting up of electrochemical cell on the surface of iron object.Hide Solution
Verified By CollegeduniaThe Correct Option is A
Solution and Explanation
When the tin coating is peeled off, the iron is exposed and rusts more quickly due to galvanic action, making Option (1) incorrect. Tin itself does not prevent rusting once it is removed.
The Correct answer is: Coating of iron surface by tin prevents rusting, even if the tin coating is peeling off.Was this answer helpful?00
