Testing for Hydrogen Gas
The other day in science we done and experiment testing for hydrogen gas.
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 glasses
Method:
1.Light Bunsen burner
2.Add you sample of metal to your test tube. Add 2 mL of acid.
3.Carefully invert the boiling tube above the test tube containing the metal and acid.
4.Hold the test tubes together for a few minuets,
5.When you think the tube is full, your lab partner should light a wooden splint
6.Carefully, but quickly,tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the tube
Observation:
The gas gets collected into the big test tube, we then put the burning splint into the test tube. As you put the splint in you'll here a noise come from it. which is quite loud and deafening
