Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
Ammonia occurs in nature and has been detected in the interstellar medium. In many countries, it is classified as an extremely hazardous substance. [15] Ammonia is produced biologically in a process called nitrogen fixation, but even more is generated industrially by the Haber process. The process helped revolutionize agriculture by providing ...
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
Its products include anhydrous ammonia, sulfur, sulfuric acid, finished fertilizers, petroleum coke, and nitric acid. [3] The company was established by Ronald Stanton in 1965, [4] and is currently headquartered in New York City. [2] [5] The company has offices in Europe, Asia, North America, South America, Middle East, and South Africa. [6]
For example, the limiting acid in liquid ammonia is the ammonium ion, NH 4 + which has a pK a value in water of 9.25. The limiting base is the amide ion, NH 2 −. NH 2 − is a stronger base than the hydroxide ion and so cannot exist in aqueous solution. The pK a value of ammonia is estimated to be approximately 34 (c.f. water, 14 [3] [4]).
The image may still be all American, but these shades aren't made in the U.S. In 1999, eye-care giant Bausch & Lomb sold the brand to Italy’s Luxottica, and the stylish shades have since been ...
Hartshorn salt, also known as hartshorn, baker's ammonia, ammonium carbonate and ammonium bicarbonate is used as a leavening agent in baked goods in place of yeast, baking soda and baking powder. It was more popular in the 1700s and prior as a forerunner of the modern baking powder [ 7 ] but is still used today in traditional German, Swiss ...
An ammonia leak at a commercial food preparation facility in Virginia sent 33 people to the hospital, authorities said Thursday. The leak at the Cuisine Solutions plant in Sterling on Wednesday ...
