Manganese in oxidation state +7 is represented by salts of the intensely purple permanganate anion MnO − 4. Potassium permanganate is a commonly used laboratory reagent because of its oxidizing properties; it is used as a topical medicine (for example, in the treatment of fish diseases). Solutions of potassium permanganate were among the ...
Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH 3 CH=CH−CH=CH−CO 2 K. It is a white salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative (E number 202). [4] Potassium sorbate is effective in a variety of applications including food, wine, and personal-care products.
Potassium methoxide is a white to yellowish, hygroscopic, odorless crystalline powder which reacts violently with water forming potassium hydroxide and methanol. The aqueous solutions obtained are highly basic and have a corrosive effect. The substance is classified as an inflammable solid with a spontaneous ignition temperature of 70 °C. [6]

The price of mercury has been highly volatile over the years and in 2006 was $650 per 76-pound (34.46 kg) flask. [51] Mercury is extracted by heating cinnabar in a current of air and condensing the vapor. The equation for this extraction is: HgS + O 2 → Hg + SO 2 Evolution of mercury price (U.S.) and production (worldwide)
