How to test Hydrogen gas?

Hydrogen Text:
1.)prepare a text tube that contain hydrogen,a match.
2.)burn the match and put in the tube.
3.)you will hear a pop sound.

Why for?
The hydrogen are very unstable, unlike noble gas, hydrogen are very reactive.
When energy transfers to the gas, they are overreactive.
If they dont combine with other substances, they will breakdown.
Common they combine with oxygen to form water(H2O) and release the sound energy.
The water is in steam(gas) form.

Note:
1:)All substance have a life time.
2:)Substance combine with substance will posepone their life time.

pop sound test
hydrogen burns with a 'pop' sound
store the gas in a stoppered test tube
take out the stopper and put a burning sprint near the mouth of the test tube
you will hear a 'pop' sound if hydrogen is present

You can use a lighted splint to put close to the test tube....a "pop" sound will be given if it is hydrogen...but you need to put extra care when you do the testing

Hope that it would help

If u put a burning splint into the test tube containing hydrogen,u will hear a
pop sound.
