Testing For Carbon Dioxide Gas!

Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid

Equipment: - Two test tubes
- Delivery tube 
- Bung
- Lighter
- Test tube rack
- Wooden splint
- Hydrochloric Acid
- Calcium Carbonate

Method: 
- Add a pea size amount of the calcium carbonate into one of the test tubes
- Place this tube in a test tube rack. Ensure you have the bung and delivery tube ready
- Add 5ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the test tube
- Holding the other test tube with your tongs, capture the gas produced in the tube
- When you think the tube is full, your partner should light a wooden splint
- Insert the burning splint into the mouth of the test tube

Observations:
When the tube connected we waited until gas collected we added the splint, the fire went out immediate and light smoke drifted out of the top of the tube.
