Potassium nitrite Potassium nitrite Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula . It is an ionic salt of potassium ions K and nitrite ions NO, 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 materials. 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. Gloves and safety glasses are usually used when handling potassium nitrite. Nitrite is present at trace levels
Potassium bisulfate bisulfate forms potassium pyrosulfate and water: Temperatures above 600 °C further decompose potassium bisulfate to potassium sulfate and sulfur trioxide: Aqueous solutions of potassium bisulfate behave as two separate, uncombined compounds, KSO and HSO. Adding ethanol to the solution precipitates out potassium sulfate. Potassium bisulfate is commonly used to prepare potassium bitartrate for winemaking. Potassium bisulfate is also used as a disintegrating agent in analytical chemistry or as a precursor to prepare potassium persulfate, a powerful oxidizing agent. Potassium bisulfate Potassium bisulfate, is an inorganic compound with the chemical formula KHSO and is the potassium acid salt of sulfuric acid.
