✔ 最佳答案
Simple put the iron nail into a cup of copper (II) sulfate solution.You may observe that the color of the solution will change from blue to green gradually.
The iron from the nail displaces copper (II).
Iron becomes iron (II) ion
and copper (II) ion becomes copper metal.
This is called a displacement reaction.
