Question

Food cans are generally coated with tin rather than zinc because _______.

• A. it is more reactive
• B. it has a lower melting point
• C. it is less reactive
• D. it is expensive

Answer 1

The correct option is A

it is more reactive

Zinc ($\text{Zn}$) is much more reactive in nature than tin. So, it reacts with the acids and bases present in the food to form harmful salts.
Hence, the food cans are generally coated with tin ($\text{Sn}$) instead of zinc($\text{Zn}$).
