The result is the production of salts. Hydrochloric Acid Some metals dissolve in this acid and this results in the formation of hydrogen gas and oxidized metal chlorides.

What Is the Test for Hydrogen Gas? | Reference

Testing for hydrogen gas involves heating hydrogen gas over a flame and listening for a distinctive pop. Because hydrogen is highly flammable, it will react to the heat. Using a flame is the best method of testing for the presence of hydrogen. Hydrogen has no color or smell and does not react to litmus paper because it is neutral.
