POTASSIUM

n.A name given to the metallic basis of vegetable alkali. According to Dr. Davy, 1 parts of potash consist of 86.1 parts of the basis, and 13.9 of oxygen. Potassium has the most powerful affinity for oxygen of all substances known; it takes it from every other compound, and hence is a most important agent in chimical analysis.

 

Webster's 1913 Dictionary

POTASSIUM

Po *tas "si *um, n. Etym: [NL. See Potassa, Potash. ] (Chem. )

 

Defn: An Alkali element, occurring abundantly but always combined, as in the chloride, sulphate, carbonate, or silicate, in the minerals sylvite, kainite, orthoclase, muscovite, etc. Atomic weight 39.. Symbol K (Kalium ).

 

Note: It is reduced from the carbonate as a soft white metal, lighter than water, which oxidizes with the greatest readiness, and, to be preserved, must be kept under liquid hydrocarbons, as naphtha or kerosene. Its compounds are very important, being used in glass making, soap making, in fertilizers, and in many drugs and chemicals. Potassium permanganate, the salt KMnO4, crystallizing in dark red prisms having a greenish surface color, and dissolving in water with a beautiful purple red color; -- used as an oxidizer and disinfectant. The name chameleon mineral is applied to this salt and also to potassium manganate. -- Potassium bitartrate. See Cream of tartar, under Cream.
