Metals and Acids

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

Method: 1. Light your Bunsen burner or use a lighter. 

               2. Add your sample of metal ti your test tube, add 2ml 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.

Discussion:

While we were doing the experiment we were trying to make a pop sound with the gases and the lit wooden splint. Once we took of the the top test tube we had to quickly put the wooden splint in the tube so as the gases impacted on each other it made a loud popping sound. In the first test tube we put metal and Sulfuric acid. 

Conclusion: 

If I were to do this another time I would hold the gases together for longer.
