Infobox references. 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 readily dissolves in water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic, and may be described as aqueous ammonia or ammonium hydroxide. [30] The maximum concentration of ammonia in water (a saturated solution) has a specific gravity of 0.880 and is often known as '.880 ammonia'. [31]
Two capsules of smelling salts from a first-aid kit. A thin inner glass tube contains alcohol and ammonia; the outer layer is cotton and netting. When crushed, the liquid is released into the cotton, while the glass shards are retained inside. The ammonia-soaked cotton is waved in front of the nose for the treatment of fainting.
G. N. Lewis realized that water, ammonia, and other bases can form a bond with a proton due to the unshared pair of electrons that the bases possess. [3] In the Lewis theory , a base is an electron pair donor which can share a pair of electrons with an electron acceptor which is described as a Lewis acid. [ 4 ]
Ammonium carbonate is a chemical compound with the chemical formula [N H 4]2 C O 3. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH4]+ and carbonate anions CO2− 3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt.
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [25] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [26] [27] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [2][3] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using a finely divided iron metal catalyst: This reaction is slightly favorable in terms of enthalpy, but is disfavored in ...
Nitrification. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.
