When a metal reacts with an acid, the same types of products are always formed.
Aim: 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 glass
Method:
- Light your Bunsen burner.
- Add your sample of metal to your test tube. Add 2 ml of acid
- Carefully invert the boiling tube containing the metal and acid (as shown in the diagram below)
- Hold the test tube 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 quick, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.
