Potassium   Listen
noun
Potassium  n.  (Chem.) 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 39.0. 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.

"Potassium" Quotes from Famous Books



... for epilepsy (not obviously fraudulent) is bromides. The usual method is to condemn vigorously the use of potassium bromide, and substitute ammonium or sodium bromide for it. Some advertisers condemn all the bromides, and prescribe a mixture of them; others condemn potassium bromide, and shamelessly forward a pure solution of this same salt in water ...

He puts lumps of cyanide of potassium, bought at the druggist's, in a bottle, and mixes plaster of Paris with water until it is like dough, and then pours it over the potassium. When it dries, the bottle is ready for use. Five cents' worth lasts a season, and is cheaper than ether, papa ...

I don't know but what all the metals, gold, silver, iron, tin, sodium, potassium, and so forth, are not different forms of hydrogen, or of something else which is the parent of hydrogen. In fact, I know but very little about the matter; except this, that I do know very little; and that the more I experiment, and the more I analyse, the more unexpected puzzles and ...

The objection to Schnbein's ozonometer (potassium iodide on starch paper) and to Houzeau's ozonometer (potassium iodide on red litmus paper) lies in the fact that their materials are hygroscopic, and their indications vary widely with the moisture of the air.

Over fifty years ago, in a memoir on "Placental Phthisis," Sir James Y. Simpson advanced a new idea in the recommendation of potassium chlorate during the latter stages of pregnancy. The efficacy of this suggestion is known, and whether, as Simpson said, it acts by supplying extra oxygen to the blood, or whether the salt itself is conveyed to the fetus, has never ...
