Summary of Steps:
1. Iron and copper (II) sulfate solution
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.
2. Lead (II) nitrate and potassium iodide solutions
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.
3. Magnesium metal and hydrochloric acid solution
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.
4. Electrolysis of water
Use a U-tube with electrodes at each end, connected to a battery. Fill the U-tube 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.
5. Burning magnesium
Place magnesium ribbon in a clean crucible (on a clay triangle above a Bunsen burner). Heat until the magnesium begins to burn.
