Question

Rahul has set up a new shop where he sells food packaged in iron containers. However, he is receiving a lot of complaints about his food being spoilt. Rahul informed his friend Rohit about this problem. Rohit recommends Rahul to use tin-coated iron containers instead. What could be the reason for this?



Your Answer
A

Because tin is cheaper than iron.

Your Answer
B

Because tin is more easily available as compared to iron.

Your Answer
C

Because tin is a better conductor of heat. So food will remain hot.

Correct Answer
D

Because tin is less reactive than iron.


Solution

The correct option is D

Because tin is less reactive than iron.


Tin cans, used for storing food, are made by electroplating tin onto iron. Tin is less reactive than iron. Thus, food does not come into direct contact with iron and is protected from getting spoilt.
