Testing for hydrogen gas
Aim: To show that hydrogen gas is produced when a metal reacts with acid.
Equipment:
Test tube
lighter
A boiling tube
Wooden splint
A bottle of acid
A piece of metal
Safety glasses
Method:
Add a sample of metal to your test tube. Add 2 ml of acid.
Carefully invert your boiling test 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 full with gas
When you think the test tube is full (wait a minute) your partner should light a wooden stick
Carefully but quickly tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.
Results: it made a popping noise
Discussion: The reactants began to bubble and smoke
Conclusion: The experiment was successful and popped as it should have and what I would change is nothing.
