Answer:
hydrogen
This test is most commonly used to identify hydrogen, which extinguishes with a distinctive 'squeaky pop' sound. Hydrogen is easily ignited, as it is flammable over a wide range of concentrations in air, making this test quite robust. If the gas is non-flammable, the burning splint will be extinguished.
