Question

Why are food cans tin-plated instead of zinc plated though zinc is cheaper than tin?
Answer:
Tin is less reactive than zinc. It is less likely to dissolve in the liquid stored in the food cans. Tin reacts only with powerful acids whereas zinc can easily react even with tomatoes, so it is not safe to store food in zinc-plated cans.
