Science experiment that really 'pops'

Watch a demonstration to see hydrogen gas produced during a chemical reaction between an acid and metals. Observe the physical changes that occur when hydrochloric acid reacts with the metal magnesium. Listen for the pop - evidence of a chemical change. When hydrochloric acid reacts with the metal zinc, is the reaction ...


The Reaction of Metals with Acid

Students use this simulation to learn that react with hydrochloric acid to produce salt and hydrogen and find out how to test for hydrogen gas. The notice that sodium reacts violently and that magnesium reacts more quickly than zinc but that the hydrogen gas test is positive for both. Word equations are provided for all reactions.
