How can you tell if a gas is hydrogen?

Answer 1

Light a wooden splint and hold it in some of the unknown gas(which is supposedly hydrogen). If there is a loud "pop" sound, then it is hydrogen. there is a very quick and simple way to do this you have to trap the gas in side a test tube but make sure it is half full of water, trap the gas and if when you turn the test tube upside down and the water stays in the same place the bottom of the tube (which would now be top) then you have "H" HYDROGEN

Answer 2

It is not sure that if gas bubbles are evolving, they must be hydrogen gas.

To check this, you can bring a burning matchstick near the mouth of vessel from which gas bubbles are emerging. If the matchstick burns with a popping sound, then the gas is hydrogen. If not then it not hydrogen.

Answer 3

One common test for hydrogen gas is the "pop test," where a burning splint makes a distinctive popping sound when exposed to hydrogen gas. Hydrogen gas is also odorless and colorless. Additionally, it is less dense than air and will rise quickly.

Answer 4

Collect the gas formed, if it burns with a pop/high pitched screech noise, it's hydrogen.

Answer 5

by using the pop test or lighting a flame near a small amount if you hear a pop then the gas is hydrogen .
