Question

10. Tin is used to coat tin cans for food storage. If the tin is scratched and the iron of

the can exposed, will the iron corrode more rapidly or less rapidly? Explain

Answer 1

Tinning is a process of thinly coating sheets of wrought iron or steel with tin to prevent it from oxidation. Thus, by scratching the tin the iron corrosion will go more rapidly since oxygen will be directly in contact.
