ammonia water[ə′mōn·yə ‚wȯd·ər]
an aqueous solution containing 18–25 percent ammonia. Ammonia water is obtained by mixing synthetic ammonia in water or by absorption of ammonia in water from the gases given off in coke production. In the latter case, ammonia water, just like ammonia (18–20 percent), contains an admixture of carbonic gas (70–100 grams per liter), an insignificant quantity of cyanic compounds, and other substances. Ammonia water is used as liquid liming in the production of soda, in industrial organic synthesis for the ammoniation of feed in agriculture, and in other industries.
