Which test is used to identify hydrogen gas?
Answer and explanation
Correct answer: Pop sound near a burning splint
Hydrogen is a combustible gas. When a sample of hydrogen is brought near a burning splint, it combines rapidly with oxygen and burns, producing the characteristic ‘pop’ sound. Thus option B is the identification test. Limewater turning milky indicates carbon dioxide, turmeric changing colour suggests a basic medium, and blue litmus remaining blue is not a specific hydrogen test.
