Metals and Acids

Testing for hydrogen gas

Aims: to show that hydrogen gas is produced when a metal reacts with acids.

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

Method: 1. Add your sample of metal to your test tube. Add 2 mL of acid.

2.  Carefully invert the boiling tube above the test tube containing the metal and acid.

3. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.

4. When you think the tube is full, your lab partner  should light a wooden splint.

5. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Observations -
I made Hydrogen gas which reacted to the metal and the wooden burning split and it worked with making the reaction.
When you added the burning wooden splint into the gas filled test tube it was a boom kinda screechy sound.
