Answer:
this is a type of displacement reaction. In this case there is displacement of copper by iron which is more reactive as compared to copper which is present in blue vitriol. As a result of this there is formation of free copper with settles at the bottom of the container.

In this question, we are asked to tell about the change that is going to take place when an iron nail is dipped in an aqueous solution.
- Reddish brown deposition of copper will take place at the bottom of the container.
- This is a displacement reaction.
- It is a displacement reaction because it is the displacement of copper by iron which is more reactive as compared to copper which is present in blue vitriol.
- As a result of this there is a free formation of copper which settles at the bottom of the container.
- The metallic copper has a reddish brown and as result, this color will be formed.
- Reaction will be CuSO4 + Fe-----> Cu + FeSO4
