Aim: To show that hydrogen gas is produced when a metal reacts with acid.
Equipment: A test tube, a boiling tube, Bunsen burner (A liters better), wooden splint, a bottle of acid, a piece of metal and safety glasses.
Method:
Light your bunsen burner (If you're using one).
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 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 if the test tube
Observations: It's called the pop test because once you insert the splint in the test tube it’ll make a slight high pitched sound / Beep.
Results: “Once you insert the splint in the test tube it’ll make a slight high pitched sound / Beep.”... Its made a pop
Discussion: We were testing for hydrogen gas
Conclusion: It worked really well because it made the pop it was supposed to make. Something I would have done differently was to get the wooden splint in the test tube faster so it would make a loud and bigger pop.
