Question

Which test should be made before collecting hydrogen in a gas jar?

Answer 1

Since Hydrogen is collected by downward displacement of water, we need to make sure that there is water in the jar and there is space for the gas to rnter the jar.

Answer 2

HLO FRNDZ..


The chemical test for hydrogen is that it burns with a pop sound.

Therefore before collecting the gas it should be tested with a burning splint, if the burning produces a pop sound, then you would know that what you are collecting is actually hydrogen gas.
