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.
3 ημέρες πριν · ammonia (NH3), colourless, pungent gas composed of nitrogen and hydrogen. It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds. Uses of ammonia. The major use of ammonia is as a fertilizer.
What is Ammonia? Ammonia is a colorless gas with a chemical formula NH 3. It consists of hydrogen and nitrogen. In its aqueous form, it is called ammonium hydroxide. This inorganic compound has a pungent smell. In its concentrated form, it is dangerous and caustic. The NH 3 chemical name is ammonia. Table of Contents. Ammonia Structure.
10 Ιουλ 2024 · Ammonia, with the formula NH3, is a clear gas that has a very strong smell. It’s made of one nitrogen atom (N) and three hydrogen atoms (H), all connected in a way that shares their electrons, making it a kind of chemical called a covalent compound.
This kind of ammonia is called liquid ammonia or aqueous ammonia. Once exposed to open air, liquid ammonia quickly turns into a gas. Ammonia is applied directly into soil on farm fields, and is used to make fertilizers for farm crops, lawns, and plants.
ammonia, Colourless, pungent gas composed of nitrogen and hydrogen, chemical formula NH 3. Easily liquefied by compression or cooling for use in refrigerating and air-conditioning equipment, it is manufactured in huge quantities. Ammonia is made by the Haber-Bosch process (see Fritz Haber).
To produce the desired end-product ammonia, the hydrogen is then catalytically reacted with nitrogen (derived from process air) to form anhydrous liquid ammonia. This step is known as the ammonia synthesis loop (also referred to as the Haber-Bosch process): 3 H 2 + N 2 → 2 NH 3
