644 Words3 Pages
PURPOSE: To observe oxidation – reduction reactions. PROCEDURE: 1. Gather the following equipments: paper towel, well plate 24, plastic tweezers, copper (II) sulfate, iron (III) chloride, iron metal, magnesium metal ribbon, magnesium sulfate, 2 pieces lead metal, sodium sulfate, zinc metal, zinc nitrate. 2. Place 10 drops of sodium sulfate into A1 of the 24 well plate. 3. Place 10 drops of magnesium sulfate into A2 of the 24 well plate. 4. Place 10 drops of zinc nitrate into A3 of the 24 well plate. 5. Place 10 drops of iron (III) chloride into A4 of the 24 well plate. 6. Place 10 drops of copper (II) sulfate into A5 of the 24 well plate. 7. Use the tweezers to pick and carefully insert a piece of magnesium into the sodium sulfate. Record your observations. 8. Carefully insert a piece of zinc into the magnesium sulfate. Record your observations. 9. Carefully insert a piece of lead into the zinc nitrate. Record your observations. 10. Carefully insert a piece of lead into the iron (III) chloride. Record your observations. 11. Carefully insert a piece of iron into the copper (II) sulfate. Record your observations. 12. Place a paper towel over the drain, pour the content of the well plate, throw the paper towel and rinse the well plate. DATA, OBSERVATIONS, AND CALCULATIONS: Data Table: Oxidation - Reduction | | Reactions | Mg in Na2SO4 | Bubbles | Zn in MgSO4 | Small bubbles | Pb in Zn(NO3)2 | Dark lead changed into lighter color | Pb in FeCl3 | Changed the lead into slight green yellow | Fe in CuSO4 | Changed the iron into orange color | Note: I added more than 10 drops to make sure that the pieces are well covered. QUESTIONS: A. Based on your observations make 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
