Laboratory, available under heated concentrated ammonia or ammonia at room temperature with concentrated aqueous ammonia and solid caustic ammonia mixing methods, which device is simple to operate, ammonia, and the resulting larger concentration of ammonia, which uses ammonia, do "fountain" experiment better. Because ammonia is volatile and unstable, so the ammonia should be sealed in a brown or dark reagent bottle, cool, dark place. Ammonia is an important laboratory reagents, mainly used as an analytical reagent, a neutralizing agent, the role of ammonia, alkaloids leaching agent, aluminum synthesis and weak alkaline solvent. Test and measurement for aluminum synthesis and certain elements (such as copper, nickel), and to precipitate the hydroxides of various elements.
