The oftentimes severe methemoglobinemia found in sodium nitrite poisoning cases results in systemic hypoxia, metabolic acidosis, and cyanosis. [50] The reported [51] signs of sodium nitrite poisoning are as follows: "Symptoms of [nitrite] poisoning can vary depending on the amount and duration of the exposure.
The nitrite ion has the chemical formula NO − 2. Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.
Sodium azide is an inorganic compound with the formula NaN3. This colorless salt is the gas-forming component in some car airbag systems. It is used for the preparation of other azide compounds. It is an ionic substance, is highly soluble in water, and is acutely poisonous. [ 5]
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. It is a strong oxidizer and may accelerate the combustion of other ...
Poisoning is relatively common following breathing in smoke from a house fire. [2] Other potential routes of exposure include workplaces involved in metal polishing, certain insecticides, the medication sodium nitroprusside, and certain seeds such as those of apples and apricots. [3] [7] [8] Liquid forms of cyanide can be absorbed through the ...
Sodium nitroprusside ( SNP ), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [3] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [3]
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
Azide. The azide anion. In chemistry, azide ( / ˈeɪzaɪd /, AY-zyd) is a linear, polyatomic anion with the formula N− 3 and structure −N=N+=N−. It is the conjugate base of hydrazoic acid HN3. Organic azides are organic compounds with the formula RN3, containing the azide functional group. [1] The dominant application of azides is as a ...
