Q: What is the correct answer for CBSE10?

The correct answer is B. Iron is more reactive than copper. Therefore, the iron nail in copper sulphate solution will displace copper, leading to a copper coating on the iron nail. The copper wire in iron sulphate solution will remain unchanged because copper cannot displace iron from its salt solution.

Q: In Activity 3.12, if copper wire is placed in iron sulphate solution and an iron nail in copper sulphate solution, what observations would confirm the relative reactivity of copper and iron?
