The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Fire: Not combustible itself but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may accelerate burning. Explosion: No danger of explosion. KNO 3 is an oxidising agent, so will accelerate combustion of combustibles. Fire Extinguishing Media: Dry chemical, carbon dioxide, Halon, water spray, or fog ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
A fire was detected on the Finnish cargo ship Tirrenia on 23 January 1953, while it was carrying ammonium nitrate. Attempts to extinguish the fire with steam were unsuccessful, and the ship was abandoned before it exploded later in the night. [11] United States Roseburg, Oregon 7 August 1959: 14 4.1
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil . The process of complete nitrification may occur through separate organisms [ 1 ] or entirely within one organism, as in comammox bacteria.
Ammonium nitrate decomposes, non-explosively, into the gases nitrous oxide and water vapor when heated. However, it can be induced to decompose explosively by detonation. [40] Large stockpiles of the material can also be a major fire risk due to their supporting oxidation, a situation which can easily escalate to detonation. Explosions are not ...
Nitromethane can be produced in the laboratory by treating sodium chloroacetate with sodium nitrite. [7] Oxidation of oximes [8] or primary amines. [9] Reduction of β-nitro alcohols [10] or nitroalkenes. [11] By decarboxylation of α-nitro carboxylic acids formed from nitriles and ethyl nitrate. [12] [13]
