Possibility of hazardous reactions
Extremely dangerous in contact with moisture or water, releasing hydrogen with sufficient heat to cause ignition or explosion. May ignite spontaneously in air or oxygen. Burns violently, accompanied by explosions which cause spattering…Very reactive. A strong reducing agent. Boron trifluoride reacts with incandescence when heated with potassium [Merck 11th ed. 1989]. Maleic anhydride decomposes explosively in the presence of potassium[Chem Safety Data Sheet SD-88. 1962]; [Chem. Haz. Info. Series C-71. 1960]. Sodium peroxide oxidizes potassium with incandescence [Mellor 2:490-93. 1946-47]. May catalyze rearrangement and polymerization of ethylene oxide liberating heat [J. Soc. Chem. Ind. 68:179. 1949].

A mixture of potassium and any of the following compounds produces a weak explosion on impact: ammonium bromide, ammonium iodide, cadmium fluoride, chromium trifluoride, manganous bromide, manganous iodide, nickel fluoride, potassium chlorocuprate, silver chloride, silver iodide, strontium iodide, thallous chloride, and zinc fluoride [Mellor 2, Supp. 3:1571. 1963]. A mixture of potassium and any of the following compounds may explode on impact: boric acid, copper oxychloride, lead oxychloride, lead peroxide, lead sulfate, silver iodate, sodium iodate, and vanadium oxychloride [Mellor 2, Supp. 3:1571. 1963]. A mixture of potassium with any of the following compounds produces a very violent explosion on impact: boron tribromide, carbon tetrachloride, cobaltous bromide, cobaltous chloride, ferric bromide, ferric chloride, ferrous bromide, ferrous chloride, ferrous iodide, phosphorus pentachloride, phosphorus tribromide, and sulfur dichloride [Mellor 2, Supp. 3:1571. 1963]. Mixture of solid potassium and solid carbon dioxide (Dry Ice) explodes when subjected to shock [Mellor 2, Supp. 3:1568. 1963]. Potassium and its alloys form explosive mixtures with chlorinated hydrocarbons [Chem. Eng. News 26:2604. 1948]. Potassium in contact with the following oxides causes an explosive reaction: potassium ozonide, potassium peroxide, or potassium superoxide [Mellor 2, Supp. 3:157. 1963].

Potassium
7440-09-7
Kalium
Potassium, metal
n/a
An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells.
Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential.
The balance between potassium and sodium is maintained by ion pumps in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell generate an action potential—a “spike” of electrical discharge.
The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function.
Potassium is also an essential mineral needed to regulate water balance, blood pressure and levels of acidity.
