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 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).
The data can be extended to include products in lower oxidation states. For example: H 2 N 2 O 2 + 2 H + + 2 e − ⇌ N 2 + 2 H 2 O; E 0 = +2.65 V. Oxidation reactions usually result in the formation of the nitrate ion, with nitrogen in oxidation state +5.
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 ...
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.
NO y is the class of compounds comprising NO x and the NO z compounds produced from the oxidation of NO x which include nitric acid, nitrous acid (HONO), dinitrogen pentoxide (N 2 O 5), peroxyacetyl nitrate (PAN), alkyl nitrates (RONO 2), peroxyalkyl nitrates (ROONO 2), the nitrate radical (NO 3), and peroxynitric acid (HNO 4).
This fire engine, used by the Toronto Fire Services, is an example of firefighting apparatus. A firefighting apparatus (North American English) [1] or firefighting appliance (UK English) [2] describes any vehicle that has been customized for use during firefighting operations.
However, even dilute nitric acid can oxidize copper to Cu 2+ ions, with the nitrate ions acting as the effective oxidant: [1] 3 Cu + 8 HNO 3 → 3 Cu 2+ + 2 NO + 4 H 2 O + 6 NO − 3. Sometimes the concentration of the acid is a factor for it to be strongly oxidizing.
