What will happen if you keep a solution of copper sulphate in an iron container for a few days? What is the reason for your observation?

• A.  The surface of iron container will develop a green layer due to corrosion caused by copper sulphate.
• B.  Copper metal will be deposited in iron container since copper is more reactive than iron.
• C.  Nothing will happen since no reaction takes place between copper sulphate and iron.
• D.  Holes will be formed in the container since iron is more reactive than copper hence iron displaces copper from a solution of copper sulphate.
