Ammonium chloride is widely used in various industries due to its versatile properties. In the medical field, it serves as an expectorant in cough medicines, helping to clear respiratory passages by thinning mucus. It is also employed in the treatment of severe metabolic alkalosis to restore acid-base balance in the body. In agriculture, it is used as a nitrogen source in fertilizers, promoting plant growth and improving soil fertility. Its ability to lower pH makes it beneficial for crops that thrive in acidic conditions. In the food industry, ammonium chloride acts as a flavoring agent in licorice and other confectionery products, providing a unique salty taste. It is also used in baking as a dough conditioner to enhance texture and volume. In industrial applications, it is utilized in metalwork as a flux in soldering and galvanizing to clean metal surfaces and improve adhesion. Additionally, it plays a role in dry cell batteries as an electrolyte, facilitating electrical conductivity. Ammonium chloride is also used in laboratories as a buffer solution to maintain stable pH levels during experiments. Its diverse applications highlight its importance across multiple sectors.
