Aqueous ammonia.

Ammonia is a binary compound of nitrogen with hydrogen (chemical formula NH3) is the most important of several known hydrogen compounds of nitrogen.

Aqueous ammonia is called a solution of ammonia in water. Aqueous ammonia is a transparent liquid (sometimes with a yellowish tinge), which has a strong odor of ammonia. This solution is also known as ammonia water.

The most widespread use of ammonia water received in the chemical industry, where it is one of the most important products. The annual volume of global production reaches 100 million tons. Ammonia water is used primarily for the receipt of nitrogen fertilizer, such as nitrate and ammonium sulphate and urea. In addition, it will be used for production of nitric acid, sodium carbonate and polymers, as well as to obtain explosives and other products of the chemical industry. Being a weak base, ammonia water in the interaction with the acid neutralizes them. Aqua ammonia is widely used as a solvent and as a refrigerant (R717) in refrigeration.

Also a 10% solution of ammonia water, known as ammonia is used in medicine.

Except for aqueous ammonia, there is also the ammonia water and analytical grade (pure for analysis), it is used as a reagent in medicine and analytical chemistry. Also ammonia reagent grade is used in chemical industries for producing chemically pure substances.

Water ammonia (ammonia water) is used in agriculture as fertilizer, animal husbandry for ammonization feed. Also, water of ammonia used as a refrigerant in refrigeration.

In industry ammonia water is used in the manufacture of fertilizers such as ammonium nitrate, urea, ammonium phosphate and other nitrogen fertilizers, used in the manufacture of dyes, soda ash, electrolytic production of manganese ferroalloys production. Including ammonia water can be used in industry and in pharmaceutical industries.
