Potassium permanganate: kholo thepa lik'hemik'hale le karabelong

Potassium permanganate ka Latin o bitsoa Kalii permanganas. lefatše ke feela permanganate potassium - potassium letsoai ka itšoara joang ea acid e mankanese. Lettering KMnO. Iteanye le diforomo manyolo tsa protheine - albuminates, sensations mele itšoara joang ena e fetisitswe tukang a ikutloa joang, ho loha, ho teneha ea moo, ha a ntse a ho ba le pholiso e le hantle le deodorant thepa le pheko ea.

Potassium permanganate ne a lokisitsoeng ke motlakase ya ho kena moea oa metsoako mankanese kapa ka ho fetola boholo bona. Mona ba bang ba itšoare ka ho permanganate potassium, ho pharaletseng sebelisoa indastering le pharmacology:

2MnO2 +3 Cl2 + 8KOH → 2KMnO4 + 6KCl + 4H2O

2K2MnO4 + 2H2O → 2KMnO4 + H2 ↑ + 2KOH.

Mona, ha re ntse re bona, a mankanese a, oxidized, e ileng a itšoara ka chloride le potassium letsoai ea limolek'hule. Bobeli banka itsoara joang ka ho pharaletseng sebelisoa indastering, kaha e endothermic potassium permanganate hlahisoang ke ho electrolysis ba mamelisise ena.

The thepa 'meleng ea permanganate potassium

Ka ea saense e ba motsoako ona o boetse o bitsoa permanganate potassium, e leng kristale e granular le foromo orthorhombic ba lefifi pherese mmala. The potassium permanganate kristale foromo bola ka futhumatsang mocheso oa 240 ° C le ka holimo, eaba ba etsa oksijene ho iphetola ha lintho. Sena se bontša ka ho ikutloa ka tsela e latelang:

2KMnO4 = K2MnO4 + MnO2 + O2.

Ntho segokanyipalo 2,703 g, / cc ya. modisekwere, seraro molare boima ba permanganate potassium - 158,03 g, / Mol. The solubility tsa metsoako ka metsi itšetlehile ka mahloriso le mocheso metsi (ya data fanoa ka Table 1).

Tafole 1. Solubility ea permanganate potassium ka thempereichara e fapaneng

Ho itšetlehile ka ka tjhelete e ya kristale a phaella ka ho metsi a mocheso fapaneng, e mong le e tharollo e tla ba le 'mala o - ho tloha fokola, palo magenta ka ea mahloriso tlaase ho pherese-bopherese - ka kakaretso. Tse ling solvents potassium permanganate kristale protrude monohalogen acetone, ammonia le joala, methyl.

Lik'hemik'hale thepa ea permanganate potassium

Ntho "potassium permanganate" ke ka toka le matla oxidizing moemeli. Ho itšetlehile ka ph ba mahareng e sebetsang sebakeng sa hae ka mefuta e sa tšoaneng ea lintho tse ntse fokotsoa hore a mankanese a ka metsoako abel ea fapaneng likhato tsa ho kena moea. Ka mohlala, ka tikoloho asiti - II, ka alkaline e - ho VI, a mahareng se nke lehlakore, ka ho latellana - ho IV.

Kopaneng ho tsepamisa mohopolo acid e sulfuric, permanganate potassium, thepa lik'hemik'hale tseo li bontša ho kena moea o etsa hore karabelong e phatloha, 'me lingoliloeng oksijene ha halefile - Mokhoa ona o sebelisoa hohle O2 tlhahiso ea ho indasteri.

Tšebeliso ea permanganate potassium

Ka laboratoring tlhahiso ea morao-rao ea permanganate potassium ajoa tswakana manyolo ka oxidant ena. The tharollo alkaline e atleha ho hloekisa le degreasing moemeli. Popular le tenyetseha kopo ya 0,1% tharollo ka moriana ka kalafo ea chesa, rinsing, disinfection, deriving chefo. Ba bang ba na bapharmasi u se ke ua lumella hore sepakbola ena kaha taelo ea Tšebeletso, ho e classified ho kotsi e phatloha. Empa u ka fumana permanganate potassium mabenkeleng lema moo e rekisoa e le manyolo ka.
