Oxidation-Reduction Series EssayPlace 10 drops of surface nitrate, Zn(N03)2 into healthy A3 of the 24-well plate. 5. Place 10 drops of smoothing iron (Ill) chloride, FeC13 into well A4 of the 24-well plate. 6. Place 10 drops of Copper (II) sulfate, Cu S04 into well A5 of the 24-well plate. 7. Take the surface solids from your LabPaq 8. Use your tweezers to pick up and carefully enwrap the piece of magnesium into the sodium sulfate. read your mirror images. 9. Carefully insert a piece of zinc into the magnesium sulfate. Record your observations. 10. Carefully insert a piece of lead into the zinc nitrate. Record your observations. 11. Carefully insert the lead into the entreat Ill) chloride.Record your observations. 12. In the same way carefully insert the iron into the copper (II) sulfate. Record your observations. 13. Place a paper towel over the drain of your sink and pour the contents of the well plate by dint of it. 14. Throw the paper towel and metal pieces in the t rash Rinse the well plate and your oxidoreduction table (below) Reactions Mg Na2S04 -+ drain wit n running water. Da sodium is stronger than magnesium, turned iron duller, little amount of bubbles Zn in MgS04 Little to no reaction Less of an reaction than the Fec13, further kind of changed color Pb in FeC13 +Changed its color made it slimy green Fe CUS04 exclusively stripped nail, turned the tip orange Conclusion I was surprised at the reaction that Iron had because although I did expect some reaction I didnt expect that much of a reaction. I was as well as surprise at how subtle Pb and Zinc and Pb in Iron could be, I smell out that this lab was beneficial in honing our observational skills as some of the reactions where starker to see at first, such as Zinc in milligram. Potential Sources of Error I feel that human error could destroy this examine because if you dont clean the well you wouldnt get an accurate response from the metal.I also thought that the pipet was hard to get the accurate amount of drops out (10). Also the time could play a role, if you recorded your observation at different points of the reduction series you might get different answers. Questions A. Based on your observations have an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too. 1. Iron, Zinc, Lead, Magnesium B. Suppose you inserted a piece of copper into a solution of nickel chloride and bserved no reaction. then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the fall into place of the well in the well plate. Where does nickel fit into your activity series? 1. Iron, Nickel, Zinc, Lead, Magnesium C. Suppose you inserted a piece of an unknown metal into a solution of zinc (II) nitrate and observed no reaction. Then if you inserted the unknown piece of the metal into the solution of iron (Il l) chloride a deposit formed on the imbue of the well in the well plate. Where does the unknown metal fit into your activity series? 1.
