It’s hard to discern the type of gas you’re dealing with by looking at it with the naked eye, since many are colorless or inert. So, it is essential for you to carry out tests using specific equipment.
The majority of tests using gas can be performed with a easy to perform. To check for hydrogen’s presence, for example, simply light a candle on the highest point of the reaction vessel. And then, watch out for a pop sound. If you hear this sound, then it is a sign that the vessel is containing hydrogen. The sound can be caused by the reaction of oxygen and hydrogen during burning, which results in water.
A splint can be used in the same way to check for oxygen. In this situation, it needs to appear to light but not be glowing. The splint that is oxygen-rich will glow if it does.
These tests may provide many details on an ingredient. To protect yourself when conducting tests, it is important to follow good lab safety while performing your test.
