Potassium Standards and Recommendations

DOT Classification: 4.3; Label: Dangerous When Wet

Potassium Specification

The IUPAC name of Potassium is potassium. With the CAS registry number 7440-09-7, it is also named as Kalium. The product's categories are Inorganic & Organic Chemicals; Inorganics, and the other registry number is 31079-13-7. Besides, it is soft silvery metal, which should be stored in kerosene or liquid paraffin. It is stable, but spontaneously combustible through the generation and ignition of hydrogen. In addition, its molecular formula is K and molecular weight is 39.09.

The other characteristics of this product can be summarized as: (1)EINECS: 231-119-8; (2)Exact Mass: 38.963707; (3)MonoIsotopic Mass: 38.963707; (4)Topological Polar Surface Area: 0; (5)Heavy Atom Count: 1; (6)Density: 0.862 g/cm³; (7)Melting point: 63.38 °C; (8)Boiling point: 759 °C; (9)Vapor pressure: 0.09 mm Hg ( 260 °C); (10)Triple point: 63 °C.

Preparation of Potassium: this chemical can be prepared by the reaction of Potassium chloride with Sodium. The reaction will occur by heating to 830 °C.

Uses of Potassium: this chemical is important in neuron (brain and nerve) function, and in influencing osmotic balance between cells and the interstitial fluid, with their distribution mediated in all animals (but not in all plants) by the so-called Na⁺/K⁺-ATPase pump. It is also used to prevent muscle contraction and the sending of all nerve impulses in animals through action potentials. Moreover, Potassium ion is a nutrient necessary for human life and health. It is used as reducing agent in organic synthesis. Furthermore, it is widely used in conjunction with loop diuretics and thiazides, classes of diuretics which rid the body of sodium and water in medicine.
