Definition of KMnO4

KMnO4
Potassium Po*tas"si*um, n. [NL. See Potassa, Potash.] (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.
KMnO4
Chameleon Cha*me"le*on (k[.a]*m[=e]"l[-e]*[u^]n), n. [L. Chamaeleon, Gr. chamaile`wn, lit., ``ground lion;' chamai` on the ground + le`wn lion. See Humble, and Lion.] (Zo["o]l.) A lizardlike reptile of the genus Cham[ae]leo, of several species, found in Africa, Asia, and Europe. The skin is covered with fine granulations; the tail is prehensile, and the body is much compressed laterally, giving it a high back. Note: Its color changes more or less with the color of the objects about it, or with its temper when disturbed. In a cool, dark place it is nearly white, or grayish; on admitting the light, it changes to brown, bottle-green, or blood red, of various shades, and more or less mottled in arrangment. The American chameleons belong to Anolis and allied genera of the family Iguanid[ae]. They are more slender in form than the true chameleons, but have the same power of changing their colors. Chameleon mineral (Chem.), the compound called potassium permanganate, a dark violet, crystalline substance, KMnO4, which in formation passes through a peculiar succession of color from green to blue, purple, red, etc. See Potassium permanganate, under Potassium.
