NH4Cl

Ammonium chloride (NH₄Cl) is a chemical compound made of ammonium ions (NH₄⁺) and chloride ions (Cl⁻). It appears as a white, crystalline substance that dissolves easily in water, forming a clear solution. Commonly used in medicine to loosen mucus and as a food additive for flavor, it also has applications in industry, such as in metal processing and batteries. NH₄Cl is produced naturally in small amounts through volcanic activity and in the human body during the breakdown of amino acids. It’s safe when used properly but can be harmful if ingested in large quantities.
