Answer:
On adding iron nail in copper sulphate the displacement reaction takes place. Iron being more reactive than copper displaces copper to form green solution of iron sulphate and copper (pinkish brown) metal is displaced. Question 2: How would you devise the procedure to show that Mg > Fe > Cu in reactivity series?
