Potassium permanganate to potassium manganate (oxidation state +6) and manganese dioxide (oxidation state +4). Oxygen gas is also liberated. Potassium permanganate poses risks as an oxidizer. Contact with skin will result in a long lasting pinkish/purple stain. Potassium permanganate Potassium permanganate is an inorganic chemical compound and medication. As a medication it is used for cleaning wounds and dermatitis. It has the chemical formula KMnO and is a salt consisting of K and ions. It is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. In 2000,
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
