The purpose of this lab is to identify the different features that come about by using oxidation reduction and recording the observations, these tests will help determine the specific qualities each solution has.
Materials:
1 Paper towels
1 Well-Plate
1 Tweezers, plastic
Experiment Bag Oxidation-Reduction
Activity Series 1 Copper (II) Sulfate, 1 M - 3 mL in Pipet
1 Iron (III) Chloride, 2 M - 3 mL in Pipet
1 Iron Metal, 2 pc in Bag 2"x 3"
Magnesium Metal (ribbon) - 2 Small Pieces in Bag 2"x 3"
1 Magnesium Sulfate, 2 M - 3 mL in Pipet
1 Lead metal, 4 small pieces in bag 2 x 3”
1 Sodium Sulfate, 1 M - 3 mL in Pipet
1 Zinc Metal - 2 Small Pieces in Bag 2"x 3"
1 Zinc Nitrate, 2 M - 3 mL in Pipet
Procedure
1. Place 10 drops of Sodium sulfate, Na2SO4 into well A1 of the 24-well plate.
2. Place 10 drops of Magnesium sulfate, Mg SO4 into well A2 of the 24-well plate.
3. Place 10 drops of Zinc nitrate, Zn(NO3)2 into well A3 of the 24-well plate.
4. Place 10 drops of Iron (III) chloride, FeCl3 into well A4 of the 24-well plate.
5. Place 10 drops of Copper (II) sulfate, Cu SO4 into well A5 of the 24-well plate.
6. Take the metal solids from your LabPaq; there should be one piece each of magnesium, zinc, and iron plus two pieces of lead.
Note: Magnesium and lead oxidize very easily and an almost invisible oxidation layer may coat the metal. To insure good reactions you should scrape the surface of those metals with a pocket knife or remove the oxidation layer by rubbing the metal pieces with steel wool or something similar. Evidence that a reaction is taking place is the formation of bubbles or a coating on the metal immersed into the solution. The formation of bubbles will take place very quickly, but it may take a few minutes to see any coating on the metal.
7. Use your tweezers to pick up and carefully insert the piece of magnesium into the sodium sulfate. Record your observations.
8. Carefully insert a piece of zinc into the magnesium sulfate. Record
