Detailed explanation-1: -Hydrogen (H2) When a burning splint is introduced to a sample of pure hydrogen gas, it will burn with a popping sound. Oxygen (O2) When a smoldering splint is introduced to a sample of pure oxygen gas, the splint will reignite.

Detailed explanation-2: -Burning (or lighted) splint test A splint is lit and held near the opening of the tube, then the stopper is removed to expose the splint to the gas. If the gas is flammable, the mixture ignites. This test is most commonly used to identify hydrogen, which extinguishes with a distinctive ‘squeaky pop’ sound.

Detailed explanation-3: -Hydrogen gas is released when metal reacts with a base. A lighted wooden splint goes pop if it is put into a test tube of hydrogen. This is because the flame ignites the hydrogen, which burns explosively to make a loud sound.
