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]

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.
(aq) signifies that the ion is aquated, with cations having a chemical formula [M(H 2 O) p] q+ and anions whose state of aquation is generally unknown. For convenience (aq) is not shown in the rest of this article as the number of water molecules that are attached to the ions is irrelevant in regard to hydrolysis. This reaction occurs ...
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.
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] −).
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 ).
The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.
