An iron nail, CuSO4.5H2O, NaCl, and H2O are placed in a test tube. List all reactions that occur.?

Can anyone help me answer this question for my AP Chemistry class? I've researched for hours on the web and can't seem to find very many answers. So far I have the following reactions. Are these correct? Am I missing any? HELP!!!





鈥?Fe + CuSO4 -%26gt; FeSO4, Iron (II) reacts with Copper (II) in an oxidation-reduction reaction.


鈥?Na + SO4 -%26gt; Na2SO4, a colorless solution.


鈥?The color change in the salt layer and the appearance of solid copper on the nails are indicators of how the copper ions have moved.


鈥?pH doesn鈥檛 change, it remains constant at 5, slightly acidic.


鈥?Cu2+ + 4Cl- -%26gt; CuCl42-. As the copper ions migrate slowly into the salt layer, the green complex ion CuCl42- forms. As the copper ions continue to move upwards they come in contact with iron atoms on the surface of the nail. A redox reacaction occurs and metallic copper appears on the surface of the nail.An iron nail, CuSO4.5H2O, NaCl, and H2O are placed in a test tube. List all reactions that occur.?
It's also possible that the water will react with the iron nail and cause oxidation.





Perhaps the ferric chloride would be produced in solution with the dissociated Cl- ion reacting with the iron in the nail.
