Question

_____ undergoes rusting a)tin b) sodium c)copper d)iron​

Answer 1

Answer:

Iron

is the correct answer

Answer 2

Iron undergoes rusting.

• Rusting is basically corrosion of iron.
• Rusting happens whenever the iron is exposed to moist air. It is basically a chemical reaction among iron,oxygen and water. (And, this chemical reaction is an oxidation reaction.)
• Due to the above-mentioned chemical reaction of rusting, hydrated ferric oxide (Fe₂O₃.xH₂O) is produced which is known as 'rust'.
• As mentioned in the first point already, rusting occurs to iron metal. There's no possibility of rusting in cases of tin,sodium or copper. That's why, iron is the correct answer to this question.
