Your stomach contains hydrochloric acid, which aids in the digestion of food. Occasionally, one can suffer from an
excess of stomach acid that leads to nausea or another condition called acid reflux. A simple way to combat excess
stomach acid is to ingest an antacid. Antacids (Figure21.9) contain a base like calcium hydroxide that neutralizes
the stomach acid. In this lesson, you will learn about acid-base neutralization reactions.
Neutralization Reactions
While neutralization reactions are all alike in many ways, it is useful to look at those involving only strong acids and
bases separately from those involving a weak acid, a weak base, or both.
