Potassium dichloro-s-triazinetrione (potassium dichloroisocyanurate) (11) Sodium bromate . Potassium nitrate techical grade . Potassium nitrate also called saltpeter or niter, a white solid soluble in water formed by fractional crystallization of sodium nitrate and potassium chloride solutions. Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2.It is an ionic salt of potassium ions K + and nitrite ions NO 2 −, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. C&L Inventory . Nitrite is present at trace levels in soil, natural waters, plant and animal tissues, and fertilizer. The rate of reaction increases with temperature, but the extent of reaction decreases. Chemical Formula: KNO2 Contact Information: Sciencelab.com, Inc. 14025 Smith Rd. Pain associated with an anginal attack disappeared rapidly, and the effect lasted for several minutes, generally long enough for the patient to recover by resting. Product form : Substance Substance name : Potassium Nitrate CAS-No. A mixture of potassium cyanide and nitrite salts may cause an explosion [Pieters 1957. p. 30]. Anne APR, Central Marin Office The most significant observation was that even a small dose of <0.5 grains (≈30 mg) given by mouth caused, at first, an increase in arterial blood pressure, followed by a moderate decrease. No external energy is used and the reactions are carried out with a small amount of O2. Other . Gloves and safety glasses are usually used when handling potassium nitrite. The aim of this study was to compare a 3% potassium nitrate/0.2% sodium fluoride mouthwash with a 0.2% sodium fluoride control mouthwash in a 6-week double-blind study. Like other nitrite salts such as sodium nitrite, potassium nitrite is toxic if swallowed, and laboratory tests suggest that it may be mutagenic or teratogenic. Saltpeter .

NFPA. Contamination by ammonium compounds can initiate spontaneous decomposition. Non Recommended Uses . [8], Potassium nitrite is stored with other oxidizing agents but separated from flammables, combustibles, reducing agents, acids, cyanides, ammonium compounds, amides, and other nitrogenous salts in a cool, dry, well ventilated location. Like other nitrite salts such as sodium nitrite, potassium nitrite is toxic if swallowed, and … Fusion with ammonium salts results in effervescence and ignition. 1.1. Reacts with acids to form toxic nitrogen dioxide gas. The resulting heat may ignite surrounding combustible material. This material contains Potassium nitrate (listed as Water Dissociable Nitrate Compounds), >99%, (CAS# 7757-79-1) which is subject to the reporting requirements of Section 313 of SARA Title III and 40 CFR Part 373. Il était aussi nommé dans l'ancienn… This page contains information on the chemical Potassium Nitrate including: 21 synonyms/identifiers; U.S. Code of Federal Regulations Title 49 Section 172 shipping regulations and proper shipping name; USDOT 2008 Emergency Response Guidebook initial response information. 0. For a time, amyl nitrite was the favored treatment for angina, but due to its volatility, it was replaced by chemically related compounds that had the same effect. However, substance will enhance an existing fire. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers. Registration dossier . [2] The pure form of nitrite was first made by the Swedish chemist Carl Wilhelm Scheele working in the laboratory of his pharmacy in the market town of Köping. REASON FOR CITATION * Potassium Nitrate is on the Hazardous Substance List because it is cited by DOT. Powdered antimony mixed with potassium nitrate explodes when heated [Mellor 9:282 1946-47]. It is an ionic salt of potassium ions K+ and nitrite ions NO2−, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. Unlike sodium nitrate it is non-deliquescent. including trade names and synonyms. OX. Potassium nitrite is the inorganic compound with the chemical formula KNO2. NFPA health hazard : 1 - Materials that, under emergency conditions, can cause significant irritation. USA.gov. 491-154. Potassium Nitrite CAS RN: 7758-09-0 Reactivities / Incompatibilities. Potassium nitrate is a chemical compound with the chemical formula K N O 3.It is an ionic salt of potassium ions K + and nitrate ions NO 3 −, and is therefore an alkali metal nitrate.It occurs in nature as a mineral, niter (or nitre in the UK). Registration dossier . 1.1.1 This code shall apply to the storage of ammonium nitrate in the form of crystals, flakes, grains, or prills including fertilizer grade as defined by Definitions and Test Procedures for Ammonium Nitrate Fertilizer, dynamite grade, nitrous oxide grade, technical grade, and other mixtures containing 60 percent or more by weight of ammonium nitrate. Barium peroxide.
