Aim: To show the hydrogen gas is produced when a metal reacts with acid.
Hypothesis: I should see bubbling from the metal, if I put a match in the test tube I should hear crackling or one big bang.
Science Experiment
Equipment: a test tube, a boiling tube, bunsen burner, wooden splint, a bottle of acid, a piece of metal, safety glasses.
Method
1. light your bunsen burner
2. Add your 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 minutes, allowing time for the inverted boiling tube to fill with gas
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 test tube.
Observations: My group saw bubbling straight away when the metal hit the acid, the metal we used was
