As ammonium nitrate is a salt, both the cation, NH + 4, and the anion, NO − 3, may take part in chemical reactions. Solid ammonium nitrate decomposes on heating. At temperatures below around 300 °C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 → N 2 O + 2 H 2 O. At higher temperatures, the following reaction ...
HNO 3 + 2 H 2 SO 4 ⇌ [NO 2] + + [H 3 O] + + 2 HSO − 4; Equilibrium constant: K ≈ 22. The nitronium ion, [NO 2] +, is the active reagent in aromatic nitration reactions. Since nitric acid has both acidic and basic properties, it can undergo an autoprotolysis reaction, similar to the self-ionization of water: 2 HNO 3 ⇌ [NO 2] + + NO − 3 ...
ammonium perchlorate, ammonium nitrate, and ammonium bicarbonate; Cisplatin ([Pt(NH 3) 2 Cl 2) is a widely used anticancer drug. Ammonia is a ligand forming metal ammine complexes. For historical reasons, ammonia is named ammine in the nomenclature of coordination compounds. One notable ammine complex is cisplatin (Pt(NH 3) 2 Cl 2, a widely ...
The anion [Ce(NO 3) 6] 2− is generated by dissolving Ce 2 O 3 in hot and concentrated nitric acid (HNO 3). [2] The salt consists of the hexanitratocerate(IV) anion [Ce(NO 3) 6] 2− and a pair of ammonium cations NH + 4. The ammonium ions are not involved in the oxidising reactions of this salt.
Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts. It is mostly used as a propellant and aerating agent for sprayed canned whipped cream, and was formerly commonly used as an ...
Dissimilatory nitrate reduction to ammonium is a two step process, reducing NO 3 − to NO 2 − then NO 2 − to NH 4 +, though the reaction may begin with NO 2 − directly. [1] Each step is mediated by a different enzyme, the first step of dissimilatory nitrate reduction to ammonium is usually mediated by a periplasmic nitrate reductase.
The Ostwald process begins with burning ammonia.Ammonia burns in oxygen at temperature about 900 °C (1,650 °F) and pressure up to 8 standard atmospheres (810 kPa) [4] in the presence of a catalyst such as platinum gauze, alloyed with 10% rhodium to increase its strength and nitric oxide yield, platinum metal on fused silica wool, copper or nickel to form nitric oxide (nitrogen(II) oxide) and ...
A maximum ammonium removal rate of 0.4 kg N/m 3 /d was achieved. It was shown that for every mole of ammonium consumed, 0.6 mol of nitrate was required, resulting in the formation of 0.8 mol of N 2 gas. In 1995, the biological nature of anammox was identified. [27] Labeling experiments with 15 NH + 4 in combination with 14 NO − 3 showed that ...
