Chemical Gas Tests

Procedure

Part 1: Hydrogen and Manganese Dioxide

1. Inserted 4mL of hydrogen into a test tube
2. Scooped a little amount of manganese dioxide on the end of a wooden splint 3. Allowed the tip of the splint to flame using the Bunsen Burner 4. Allowed the reaction to proceed for a total of 15 seconds. 5. Placed the glowing splint into the test tube

6. Recorded the results

Part 2: Magnesium strip and Hydrochloric acid

1. Poured 3mL of hydrochloric acid into a test tube
2. Placed the magnesium strip into the hydrochloric acid into the tube and immediately covered the tube with a rubber stopper. 3. Allowed the magnesium strip to dissolve completely.
4. Carefully inserted a burning splint into the test tube.
5. Recorded the results.

Part 3: Vinegar and Sodium Bicarbonate (Baking Soda)

1. Poured 4mL of Vinegar into a test tube.
2. Lit the tip of a splint on fire using the Bunsen Burner.
3. Scooped a small amount of sodium bicarbonate.
4. Carefully added the sodium bicarbonate into the test tube. 5. Allowed the Vinegar and Baking Soda to react for 5 seconds. 6. Slightly tilted the test tube and inserted the burning splint halfway through. 7. Recorded the results.
