Fire extinguisher test - Science

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

Method:

1. Add a pea sized amount of the metal carbonate into one of the boiling tubes.

2. Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready.

3. Add 5 ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.

4. Holding the other boiling tube with your tongs, capture the gas produce in the other test tube.

5. Wait about 1 minute so the tube will be full and then get your partner to light the wooden splint.

6. When the test tube is full of gas, then carefully remove the tube from underneath the delivery tube.

7. Then carefully place the burning splint into the test tube.

Result: This experiment lead to the gas we made by adding hydrochloric acid and sodium carbonate to produce sodium chloride + oxygen + water, this gas cause it to put the lit splint out.

Discussion: We used hydrochloric acid + sodium carbonate = Sodium chloride + oxygen + sodium chloride to create this gas.

Conclusion: It did work it was to show what gas puts out fires like a fire extinguisher uses the same type of gases we used to put out the flame on the splint.
