Ammonium carbonate is widely used in the food industry as a leavening agent in baked goods like cookies, crackers, bread, and cakes. It helps dough rise by releasing carbon dioxide and ammonia gases when heated, creating a light and airy texture. In the pharmaceutical sector, it serves as an active ingredient in some cough medicines, expectorants, and smelling salts, aiding in the relief of respiratory conditions and used to revive individuals experiencing fainting or dizziness. In the textile and leather industries, it acts as a mordant in dyeing processes, helping fix dyes to fabrics, and is employed in leather tanning to adjust pH and condition hides before processing. Additionally, it functions as a chemical intermediate in the synthesis of various compounds and finds application in fire extinguishers as a source of ammonia gas to suppress flames.
