Therefore, he decided to try the effect on a patient of inhaling amyl nitrite, a recently synthesized compound and one that his colleague had shown lowered blood pressure in animals. Reacts with acids to form toxic nitrogen dioxide gas. Registration dossier . [3], Potassium nitrite forms potassium nitrate when heated in the presence of oxygen from 550 °C to 790 °C. listed below. Safety Data Sheet according to 29CFR1910/1200 and GHS Rev. Mixture of germanium nitrate and potassium nitrate explodes when heated. 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). Regulatory information United States of America Inventory Component CAS-No … It is used to make explosives, matches, fertilizer, fireworks, glass and rocket fuel. : 231-554-3 Molecular Weight : 84.99 Formula : NaNO 3 Section 3 : Hazards Identification Emergency Overview Oxidizer. When titanium is heated with potassium nitrate, an explosion occurs. Clean Air Act: This material does not contain any hazardous air pollutants. Other identifiers . Pyrophoricity. Page 4 of 4 MSDS - Sodium Nitrate 8. Salt peter . Potassium Nitrate is a transparent, white or colorless, crystalline (sand-like) powder or solid with a sharp, salty taste. Melting together with an ammonium salt leads to a violent explosion [Von Schwartz 1918 p. 299]. 7440-09-7 . From 650 °C to 750 °C, as the case of decomposition of potassium nitrate is, the system attains equilibrium. Appendix 1 Mixing with liquid ammonia forms dipotassium nitrite, … A mixture of potassium cyanide and nitrite salts may cause an explosion [Pieters 1957. p. 30]. ; Nitric acid potassium salt; Niter Recommended Use Laboratory chemicals.
