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 tert-butoxide Potassium tert-butoxide Potassium "tert"-butoxide is the chemical compound with the formula K(CH)CO. This colourless solid is a strong base (pKa of conjugate acid around 17), which is useful in organic synthesis. It exists as a tetrameric cubane-type cluster. It is often seen written in chemical literature as potassium "t"-butoxide. The compound is often depicted as a salt, and it often behaves as such, but it is not ionized in solution. Potassium "t"-butoxide is commercially available as a solution and as a solid, but it is often generated "in situ" for laboratory use because samples are so sensitive and older samples
