Solution

To test for the gas that is liberated when HCL (hydrochloric acid) reacts with an active metal, you can follow these steps:

  1. Set up your experiment: In a test tube, add a small piece of the active metal. Carefully add a few drops of hydrochloric acid (HCL).

  2. Observe the reaction: You should see bubbles forming in the test tube. This is the gas being produced by the reaction.

  3. Test the gas: To identify the gas, you can use the pop test. This involves collecting some of the gas in a test tube, then bringing a lit splint to the mouth of the test tube.

  4. Identify the gas: If the gas is hydrogen, it will ignite with a 'pop' sound. This is because hydrogen is highly flammable and will react with the oxygen in the air to produce water, which is heard as a 'pop'.

Remember to always follow safety guidelines when conducting experiments. Wear protective clothing and eyewear, and work in a well-ventilated area.
