A week ago we did an experiment on testing for hydrogen gas, the aim was to show that hydrogen gas is produced when a metal reacts with acid.
Equipment: a test tube, a boiling tube, bunsen burner, wooden splint,a bottle of acid, a piece of metal, safety glasses.
Method:
Light your bunsen burner.
Add a 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.
Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill the gas.
When you think the tube is full, your partner should light the 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.
Observations: it made a loud popping noise
my experiment made a really loud noise because I only waited about 20- 30 seconds instead of a few minutes.
