WebScience Chemistry Potassium permanganate (KMnO4) standard solution is prepared by dissolving 1.58 grams of potassium permanganate salt in 1.0 L of distilled water. Adjustment of this solution is done with sodium oxalate (Na2C204). 12 mL of this solution was spent in the titration of 0.0501 g sodium oxalate in acidic medium. Potassium is the chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first … See more The English name for the element potassium comes from the word potash, which refers to an early method of extracting various potassium salts: placing in a pot the ash of burnt wood or tree leaves, adding … See more Potassium is formed in supernovae by nucleosynthesis from lighter atoms. Potassium is principally created in Type II supernovae via an explosive oxygen-burning process. … See more Potassium metal was first isolated in 1807 by Humphry Davy, who derived it by electrolysis of molten KOH with the newly discovered voltaic pile. Potassium was the first metal that was … See more Potassium is the eighth or ninth most common element by mass (0.2%) in the human body, so that a 60 kg adult contains a total of … See more Physical Potassium is the second least dense metal after lithium. It is a soft solid with a low melting point, … See more Potash is primarily a mixture of potassium salts because plants have little or no sodium content, and the rest of a plant's major mineral content consists of calcium salts of relatively low solubility in water. While potash has been used since ancient times, its … See more Elemental potassium does not occur in nature because of its high reactivity. It reacts violently with water (see section Precautions below) and also reacts with oxygen. See more led headlamp usb rechargeable
