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, 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
2. Add a pea sized amount of 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 5ml 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: The one that had the most rust was the tube that had water in it and the one that had the least amount of rust was the one wrapped in aluminuim.
Conclusion: In conclusion the water tube turned out as expected and a lot of the other ones didnt have that much rust at all such as the nail polish and the aluminuim.
