1. Iron (III) and copper (II) sulfate solution
2. Fill a small test tube halfway with copper (II) sulfate solution. Add a 2.0 gram iron rod to the solution and observe the reaction.
5. Lead (II) nitrate and potassium iodide solutions
6. Pour about 2.0 mL of lead (II) nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your observations of the reaction. 7.
9. Magnesium metal and hydrochloric acid solution
10. Place one scoop of magnesium turnings into the test tube. Add hydrochloric acid slowly and observe the reaction. Next, place a burning splint near the mouth of the test tube to test for the presence of hydrogen gas.
13. Electrolysis of water
14. Use a Utube with electrodes at each end, connected to a battery. Fill the Utube with water. Turning on the battery, observe the results at each electrode. Next, test for hydrogen and oxygen gas produced at each end of the tube. 15.
17. Burning magnesium
18. Place magnesium ribbon in a clean crucible (on a clay triangle above a Bunsen burner). Heat until the magnesium begins to burn.
