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 Potassium bisulfate Potassium bisulfate, is an inorganic compound with the chemical formula KHSO and is the potassium acid salt of sulfuric acid. Mercallite, the mineralogical form of potassium bisulfate, occurs very rarely. Misenite is another, more complex, form of potassium bisulfate. Potassium bisulfate is prepared by neutralizing sulfuric acid with an equal molar amount of a potassium containing base, for example potassium hydroxide: Potassium bisulfate is also formed by the union of sulfuric acid with potassium sulfate: Potassium bisulfate is also the main by-product in the production of nitric acid from potassium nitrate and sulfuric acid: Thermal decomposition of potassium
