Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Magnesium, manganese, and zinc liberate H 2: Mg + 2 HNO 3 → Mg(NO 3) 2 + H 2 Mn + 2 HNO 3 → Mn(NO 3) 2 + H 2 Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2
The compound is a salt with separated hydroxyammonium and nitrate ions. [2] Hydroxylammonium nitrate is unstable because it contains both a reducing agent (hydroxylammonium cation) and an oxidizer (), [3] the situation being analogous to ammonium nitrate.
In response to changes in mining technology, the product line expanded to include blasting agents based on ammonium nitrate and nitric acid in the 1940s. [7] Ammonium nitrate was produced from anhydrous ammonia and air (the DuPont process) beginning in the 1950s. [7] The original nitroglycerine-based products were phased out by 1983. [2]

Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of nitric acid ( H N O 3 ), dinitrogen tetroxide ( N 2 O 4 ) and a small amount of water . The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide .
Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. After the solution is formed, typically at about 83% concentration, the excess water is evaporated off to leave an ammonium nitrate (AN) content of 95% to 99.9% concentration (AN melt), depending on ...
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 ...
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.
