In conclusion, sodium bicarbonate is much more than a simple leavening agent. Its interactions with acids highlight its diverse applications in health, environmental science, and education. Whether used in the kitchen, as a remedy for acid indigestion, or as a cleaning agent, sodium bicarbonate's ability to neutralize acids underscores its importance and versatility. Understanding these interactions not only enhances our appreciation of this everyday compound but also invites further exploration into the fascinating world of chemistry.

3. Preservatives To extend the shelf-life of baked goods, preservatives are often added to inhibit mold growth and bacterial development. Common preservatives like calcium propionate and sorbic acid help maintain freshness and prevent spoilage, enabling bakeries to reduce food waste and ensure product availability over time.
