It has a high heat of vaporization (23.3 kilojoules per mole at its boiling point) and can be handled as a liquid in thermally insulated containers in the laboratory. A form of liquid ammonia made from fermented urine was used for dyeing clothing in the Middle Ages. CAS Registry No. Ammonia from the gills of fish, their urine, and rotting food or decaying plant matter are contributors of ammonia in an aquarium. Physical measurements, including electrical-conductivity studies, provide evidence that this blue colour and electrical current are due to the solvated electron. Do not mix ammonia with chlorine bleach, as this produces toxic gases called chloramines. Ammonia is a basic building block for ammonium nitrate fertilizer, which releases nitrogen, an essential nutrient for growing plants, including farm crops and lawns. Strong, briny cheeses like brie can also smell like ammonia. Ammonia also is effective at breaking down household grime or stains from animal fats or vegetable oils, such as cooking grease and wine stains. Author of. It is produced naturally in the human body and in nature—in water, soil and air, even in tiny bacteria molecules. Ammoniak is een anorganische verbinding van stikstof en waterstof met als brutoformule NH 3.De structuur van de verbinding is niet vlak, maar neemt als gevolg van het vrij elektronenpaar op stikstof een trigonaal piramidale moleculaire geometrie aan. ammonia synonyms, ammonia pronunciation, ammonia translation, English dictionary definition of ammonia. Ammonia has a very distinct, pungent odor, described as similar to sweat or cat urine. The electrical conductivity decreases, and there is evidence that the solvated electrons associate to form electron pairs. As the concentration of dissolved metal increases, the solution becomes a deeper blue in colour and finally changes to a copper-coloured solution with a metallic lustre. Odour: Ammonia-like Canadian TDG: UN1005 Ammonia levels. It is converted to the less toxic substance urea prior to excretion in urine by the kidneys. Users of any chemical should always read the label and follow the manufacturer's instructions to avoid damaging surfaces or harming themselves or others during use. Ammonia and amines have a slightly flattened trigonal pyramidal shape with a lone pair of electrons above the nitrogen. Ammonia is a chemical. Cancer: Ingredients linked to cancer in government, industry or academic studies or assessments. It also is used in the manufacture of pharmaceuticals. Appearance: Colourless gas. Ammonia occurs naturally in the environment, so everyone is exposed to low levels at one point or another. Let us know if you have suggestions to improve this article (requires login). Hydrazine, N2H4, is a molecule in which one hydrogen atom in NH3 is replaced by an ―NH2 group. In human health, ammonia and the ammonium ion are vital components of metabolic processes. It’s also possible to be exposed to higher levels of ammonia if a person spends time in an enclosed building that contains lots of animals. Ammonia is an essential mammalian waste product for DNA, RNA, and protein synthesis and is necessary for maintaining acid-base balance. Ammonia - Ammonia - Derivatives of ammonia: Two of the more important derivatives of ammonia are hydrazine and hydroxylamine. However, excess nitrogen is excreted through urine and feces and during manure decomposition ammonia […] n. 1. Ammonia, also known as NH3, is a colorless gas with a distinct odor composed of nitrogen and hydrogen atoms. Define ammonia. Ammonia is produced and used endogenously in all mammalian species. Ammonium is largely found in a range of salts like ammonium chloride, ammonium carbonate and ammonium nitrate. Its boiling point is −33.35 °C (−28.03 °F), and its freezing point is −77.7 °C (−107.8 °F). Cheeses even have small amounts of ammonia in them, as a natural by-product of the cheese aging process. Print Ammonia can be used to purify water supplies and as a building block in the manufacture of many products including plastics, explosives, fabrics, pesticides and dyes. Ammonia, also known as NH 3, is a colorless gas with a distinct odor composed of nitrogen and hydrogen atoms. Ammonia occurs naturally and is found throughout the environment in soil, air, and water. Ammonia (NH3) is one of the most commonly produced industrial chemicals in the United States. The melting point of ammonia is -77.73 o C and the boiling point is about -33.34 o C. When considering the density of ammonia, it is lighter than air. If your body can't process or eliminate ammonia, it builds up in the bloodstream.
