Students know that the stomach contains acid and that too much acid may cause heartburn. Use this fascinating demonstration to show students the biology and chemistry of how an antacid alleviates heartburn. With a little help from MOM—milk of magnesia—and universal indicator, students will clearly see the neutralizing effect of magnesium hydroxide on stomach acid. Colorful demonstration is sure to provoke interesting discussions about the chemistry of other over-the-counter medications and the biochemistry of the human body. Includes detailed instructions with discussion of the chemical and biological processes, student worksheet and enough materials to perform the demonstration seven times.
Concepts: Acid–base neutralization, digestion, antacids. Time Required: 15 minutes Materials Provided: Milk of magnesia, hydrochloric acid, universal indicator solution, pipets.
