Question

Rahul has started a new shop where he sells food packed in iron containers. But he is receiving a lot of complaints about the spoilage of food. He tells his friend Rohit about this problem. Rohit suggests him to use tin coated iron instead. What could be the reason for this?

• A. Because tin is cheaper than iron.
• B. Because tin is more easily available as compared to iron.
• C. Because tin is a better conductor of heat. So food will remain hot.
• D. Because tin is less reactive than iron.

Answer 1

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.
