Use

Ammonium hydroxide is utilized in numerous applications: Ammonium hydroxide is used as a cleaning agent and sanitizer in many household and industrial cleaners. Ammonium hydroxide is also used in the manufacture of products such as fertilizer, plastic, rayon and rubber. Aqueous ammonia is corrosive to aluminum alloys, copper, copper alloys, and galvanized surfaces. Aqueous ammonia is an excellent acid neutralizer. In furniture making, ammonium hydroxide is used to darken or stain wood containing tannic acid. In food production, ammonium hydroxide is used as a leavening agent or acidity regulator and is classified by the Food and Drug Administration as generally recognized as safe (GRAS). Its pH control abilities make it an effective antimicrobial agent. Ammonium hydroxide is also used to treat straw, producing ammoniated straw that is edible for cattle. In the tobacco industry, ammonium hydroxide is used for flavor enhancement and as a processing aid. Aqueous ammonia is used in the laboratory most often as a complexant and base in inorganic analysis. It can dissolve silver residues, and when used with copper (II) solutions, provides a deep blue coloration.
