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.

5 天之前 · Potassium nitrite is prepared by the reduction of potassium nitrate. It reacts with cold dilute mineral acids to give nitrous acid and is also able to behave as a reducing agent (if oxidized to the nitrate) or as an oxidizing agent (if reduced to nitrogen).

Common Name: POTASSIUM NITRITE CAS Number: 7758-09-0 DOT Number: UN 1488 ----- HAZARD SUMMARY * Potassium Nitrite can affect you when breathed in. * Contact can cause severe skin irritation and burns. * Repeated skin contact can cause dryness, cracking or rash. * Breathing Potassium Nitrite can irritate the nose, throat

2023年10月24日 · Potassium nitrite forms potassium nitrate when heated in the presence of oxygen from 550 °C to 790 °C. Heating potassium nitrite above 538 °C may cause it to decompose violently and even explode, under certain conditions.

Nitrites are more potent methaemoglobin formers than nitrates, but nitrate can be converted into nitrite by intestinal bacteria. Inhaled nitrites (amyl and butyl nitrites) produce little methaemoglobin unless the liquid is swallowed, when severe toxicity may occur.

Potassium nitrite has been used for determining the bacteriostatic and fungistatic activity of acidified nitrite. It has also been used as a supplement in buffer for investigating the impact of nitrite on nosocomial pathogens including C. difficile spores.

POTASSIUM NITRITE is an oxidizing agent. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. Contamination by ammonium compounds can initiate spontaneous decomposition. The resulting heat may ignite surrounding combustible material. Reacts with acids to form toxic nitrogen ...
