Ammonium nitrate is a chemical compound with the formula NH 4 NO 3. It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, but does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer. [5]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Any salt containing the ion, such as ammonium cyanate, is called a cyanate. The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [1] The cyanate ion is an ambidentate ligand, forming complexes with a metal ion in which either the nitrogen or oxygen atom may be the electron-pair donor.
The nitronium ion, [N O 2] +, is a cation. It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH 4 ] + . It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule NO 2 , or the protonation of nitric acid HNO 3 (with removal of H 2 O ).
Peroxynitrite is weakly basic with a pK a of ~6.8.. It is reactive toward DNA and proteins.. ONOO − reacts nucleophilically with carbon dioxide. In vivo, the concentration of carbon dioxide is about 1 mM, and its reaction with ONOO − occurs quickly.
Iron(III) sulfate (or ferric sulfate), is a family of inorganic compounds with the formula Fe 2 (SO 4) 3 (H 2 O) n. A variety of hydrates are known, including the most commonly encountered form of "ferric sulfate". Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes. Solutions of ferric sulfate are also used in ...
In organic chemistry, it may also refer to the group −O−N=N−O−, or any organic compound with the generic formula R 1 −O−N=N−O−R 2, where R 1 and R 2 are organic groups. [1] Such compounds can be viewed as salts and esters of hyponitrous acid. An acid hyponitrite is an ionic compound with the anion HN 2 O − 2 ([HON=NO] −).
