What sound is heard when a burning splint is brought near hydrogen gas?
Answer and explanation
Correct answer: Pop sound
Hydrogen is a combustible gas. When a burning splint is brought near hydrogen mixed with air, the gas burns rapidly and produces a characteristic ‘pop’ sound. This sound is used as a simple laboratory test for hydrogen, although the test must be performed carefully and with a small quantity. A bell or whistle is not produced, and the gas does not remain completely silent. Therefore, option A is correct.
