Ammoniacal nitrogen (NH 3 –N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ammonia, and returned to ammonia via organic processes, in water or waste liquids.
Liquid ammonia is the most commonly studied, and best known, non-aqueous ionizing solvent. The most notable property of this compound is its ability to dissolve alkali metals to form strongly coloured, electrically conductive solutions that contain solved electrons.
Ammonia solutions (containing more than 35% but not more than 50% ammonia) appears as a clear colorless liquid consisting of ammonia dissolved in water. Corrosive to tissue and metals. Although ammonia is lighter than air, the vapors from a leak will initially hug the ground.
"Household ammonia" or "ammonium hydroxide" is a solution of NH 3 in water. The strength of such solutions is measured in units of baume ( density ), with 26 degrees baume (about 30 weight percent ammonia at 15.5 °C) being the typical high concentration commercial product. [4]
Properties. Liquid NH 3. Solid NH 3. Two visible states of NH 3. Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules.
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).
23 Μαΐ 2018 · Ammonia molecules possess a pyramidal shape, with the nitrogen atom at the vertex. These molecules continually undergo a type of motion called inversion, in which the nitrogen atom passes through the plane of the three hydrogen atoms like an umbrella turning inside out in the wind.
