Question

Food can are coated with Tin and not with Zinc because

• A. Zinc is costlier than Tin
• B. Zinc has a higher melting point than Tin
• C. Tin is less reactive than Zinc and a nontoxic metal
• D. Zinc is less reactive than Tin

Answer 1

The correct option is C

Tin is less reactive than Zinc and a nontoxic metal

The explanation for the correct answer

Option C: Tin is less reactive than Zinc and a nontoxic metal

• Zinc is more reactive than Tin.
• Tin ($\mathbf{Sn}$) only reacts with very strong acids.
• However, Zinc can react with simple acids found in food.
• Hence, in order to prevent food poisoning, the food cans are coated with less reactive metal like Tin.
• Therefore, the correct option is (C). Food can are coated with Tin and not with Zinc because Tin is less reactive than Zinc and a nontoxic metal.
