Hydrogen gas is identified by which sound?

Answer and explanation

Correct answer: Pop sound

Hydrogen is tested by bringing a lighted splint near the gas, using proper laboratory safety. Hydrogen burns rapidly with oxygen and produces a characteristic ‘pop’ sound, so option A is correct. A bell or whistle is unrelated to this chemical test, and saying that no sound is produced would miss the identifying observation. The test follows hydrogen’s combustion property.
