Question

Can we store copper sulphate in iron container and why?

• A. No, because Cu is more reactive than iron
• B. No, because iron is more reactive than copper, therefore reaction will take place.
• C. Yes, because copper is less reactive than iron.
• D. Yes, because copper is more reactive than iron.

Answer 1

The correct option is B No, because iron is more reactive than copper, therefore reaction will take place.

$Fe+CuS{O}_4\to FeS{O}_4+Cu$
Reaction has taken place because Fe is more reactive than Cu, therefore we cannot store.
