Today's experiment in science included us making carbon dioxide in a tube then putting a wooden splint on fire inside it causing the fire to disappear because there was no oxygen in it.
Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid.
Equipment: Two boiling tubes, delivery tube and bung, Bunsen Burner/lighter, test tube rack, wooden splint, a bottle of acid, small amount of metal carbonate, test tube tongs, safety glasses
Method:
1. Light your Bunsen burner/ Or use lighter
2. Add a 'pea-sized' amount of the metal carbonate into one of the boiling tubes.
3. Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready.
4. Add 5 mL of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.
5. Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below.
Results: What happened was when we add acid and a piece of metal carbonate with then sealed it with a bung and a delivery tube into a empty one, the empty one was filled carbon dioxide and when we put a fire in the carbon dioxide filled tube it just went out.
We also did this with limewater where we pretty much did the same thing but put limewater into the empty tube which just became cloudy which means carbon dioxide is present.
Discussion: Didn't know you could produuce carbon dioxide and forgot that fire needed oxygen. It was a alright experiment.
Conclusion: This experiment didn't require much work just lots of tools needed.
