2-1B Lab: Generating and Burning Hydrogen Gas

2-1B Lab: Generating and Burning Hydrogen Gas:

Analyze:
1. The zinc starts to bubble and the bubbles surrounds the zinc. It does not change the colour of the zinc but, it does change the colour of the water. Eventually the water will become white.
2. Eventually the zinc might start to change colour if left in for a very long time, but another thing that could happen is that it starts to disintegrate.
Conclude And Apply:
1. The appearance of the zinc is still its original colour (silver/grey) and there are many bubbles surrounding it and continuously moving.
2. The gas was put into a test tube.The tube was then turned over and a a glowing wood splint was put to the spout of the test tube resulting in an explosion sounding like a high pitched "pop".
