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.
