Metals for Hydrogen Gas
Aim: To show that hydrogen gas is produced when a metal reacts with acid.
Method:
- Light your bunsen burner.
- Add your sample of metal to your test tube. Add 2 mL of acid.
- Carefully invert the boiling tube above the test tube containing the metal and acid (as shown in the diagram below).
- Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.
- When you think the tube is full, Your lab partner should light a wooden splint.
- Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.
Observation: It will make a loud popping sound.
