How can you prove you have made hydrogen gas?

Answer 1

Take a sample of the gas in a test tube.

Place a lighted splint/taper to it. If it 'pops' , then it is hydrogen.

This is the classic hydrogen test.

NB When testing for hydrogen keep the test/boiling tube upside down because hydrogen being a lighter gas than air will remain in the tube.

Answer 2

You can prove you have made hydrogen gas because you will see bubbles rising from the soloution.You could also get a very tiny amount of the gas and hold a match to it.If it lights the it is most likely to be hydrogen gas

+++

The bubbles only prove A gas is being evolved. They do not indicate WHICH gas.

Answer 3

An easy way to prove that hydrogen is a gas (but it can also be a liquid and a solid) is to show someone the Periodic Table, where it shows a picture of a balloon, which shows that hydrogen's normal state is a gas.

Answer 4

You can prove you have made hydrogen gas by capturing the gas in a container and conducting a pop test using a lit splint. If the gas ignites with a "pop" sound, it indicates the presence of hydrogen gas. Additionally, you can test the gas with a flame; hydrogen burns with a pale blue flame.

Answer 5

Trap the gas in a test tube, A glowing splint inserted in the tube will pop. This shows that it is flammable.
