Caption: Test for hydrogen gas. In the test tube, hydrochloric acid reacts with magnesium metal, producing hydrogen gas. The gas passes through the glass tube and is collected over water in a test tube. A lit splint held to the end of the test tube ignites the hydrogen gas with a characteristic squeaky pop.
