Testing Hydrogen gas

Testing for Hydrogen Gas:

Aim:
To show the 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 your Bunsen Burner
2. Add your sample of metal to your test tube. Add to 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 test 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.


When the metal went in the acid it started to sizzle a bit forming smoke. After putting the other test tube over it nothing really was occurring. We lit the fire then put it in the test tube. Gas started forming on the rims of the test tube. After displaying that, there was a loud bang-like sound. That's when you know it works.
