Q
Metals and Non-metals

Question:

Food cans 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) zinc is less reactive than tin

(d) zinc is more reactive than tin

Answer:

The reactivity series is a list of metals arranged in the order of their activities. Zinc is the metal that lies above than tin in the reactivity series. This means that zinc is more reactive than tin. So, zinc can easily react with chemicals present in the food items and can deteriorate it. Hence, food cans are coated with tin and not with zinc.

Therefore, the correct answer is (d) zinc is more reactive than tin.
