Hydrogen Gas Experiment:
Aim: To show that hydrogen gas is produced when metal reacts with acid.
Equipment: A test tube, a boiling tube, bunsen burner, wooden splint, a bottle of acid, a peice of metal, safety glasses
Method: 1. Light your bunsen burner
2. Add your 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.
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.
Results: When the acid went with the magnesium it fizzed up, then warmed up, next we lit a wooden splint and put it into the tube a big pop formed almost making us students deaf.
Conclusion: When the hydrogen gas ignited It reacted with the oxygen in the air which released energy
Magnesium Oxide Experiment:
Aim - To make a metal oxide and observe the difference in properties of the product compared to the reactants.
Equipment - A piece of magnesium, bunsen burner, safety glasses, metal scissor tongs.
Method - 1. Light your bunsen burner.
2. Hold your peice of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the magnesium.
3. Place the other end of the magnesium into the bunsen burner (at the top of the blue flame).
4. When the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes.
Results: The magnesium ribbon burns with a very bright white light. A white smoke is produced as it burns. When the reaction is over a white powdery substance remains.
Conclusion: The white light is formed because the magnesium reacts with the oxygen to produce magnesium oxide releasing energy.
