Description

Technical Field

[0002] Ammonia water, also known as ammonia water, refers to an aqueous solution of ammonia. Its main components are NH₃·H₂O. It is colorless, transparent, and has a pungent odor. Ammonia water is volatile and has some alkaline properties. It is produced by bubbling ammonia gas into water. Industrial ammonia water is an aqueous solution containing 25% to 28% ammonia. Only a small portion of the ammonia molecules react with water to form ammonium ions and hydroxide ions, i.e., ammonia monohydrate, a weak base found only in ammonia water. The freezing point of ammonia water is related to its concentration. The commonly used freezing point of 20% (mass fraction) ammonia water is approximately -35°C. The neutralization reaction of ammonia water with acid generates heat, posing an explosion hazard.
