Answer 2

Answer:

• Hydrogen gas is liberated when an active metal reacts with hydrochloric acid.
• For testing the presence of hydrogen gas, bring a burning candle near the mouth of the test tube in which the reaction is taking place.
• If the gas burns with a popping sound, then it can be concluded that it is hydrogen.
