Metals and Acids:

Metals and Acids:

Aim: To show that hydrogen gas is produced when a metal reacts with acid.

Equipment: A test tube, a boiling, Bunsen burner,wooden splint,a bottle of acid,a piece of metal, safety glasses.

Method:
1. Light you Bunsen burner
2. Add you sample of metal to your test tube. Add 2ml of acid.
3. Carefully invert the boiling tube above the test tube containing the metal and acid (as shown in the diagram below).
4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with glass
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. 

Result: When gas was formed we quickly put the wooden splint that was on fire into the test tube which mad a loud popping noise.

Discussion: Basically we put Magnesium and Hydrochloric acid in one test tube and put another bigger test tube over it which started to make a gas form. As Magnesium and Hydrocloric acid were mixed together they formed bubbles and started to get hot. When the hydrogen gas was in contact with oxygen it made a big pop noise.

Conclusion: The experiment was really fun I really enjoyed it and loved to see everyone get scared with the popping noise. It would be fun to do this experiment again but next time I would like to put the splint in the test tube.
