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 studies because potassium is a macronutrient required for life. Potassium is formed in supernovae by nucleosynthesis from lighter atoms. Potassium is principally created in Type II supernovae via an explosive oxygen-burning process. is also formed in s-process nucleosynthesis and the neon burning process. Potassium is the 20th most abundant element in the solar system and the 17th most abundant element by weight in the earth. It makes up about 2.6% of the weight of the earth's crust and is the seventh most abundant element in the crust. The potassium concentration in seawater is 0.39 g/L (0.039 wt/v%), about one twenty-seventh
