Potassium permanganate: isi chemical Njirimara na mmeghachi omume

Potassium permanganate na Latin na-akpọ Kalii permanganas. The ụwa bụ nnọọ a potassium permanganate - potassium nnu na mmeghachi omume nke manganese acid. Lettering KMnO. Kpọtụrụ na organic forms of protein - albuminates, ahụ sensations na a mmeghachi omume na-ebugharị na-ere sensashion, knitting, obodo iyatesịt, mgbe na-enwe a na-agwọ ọrịa mmetụta na deodorant onwunwe na ngwọta.

Potassium permanganate na-akwadebe site electrochemical ọxịdashọn nke manganese ogige ma ọ bụ site na-agbanwe ha n'ike-n'ike. Lee ụfọdụ Jeremaya mere ka potassium permanganate, na ọtụtụ-eji ụlọ ọrụ na pharmacology:

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

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

Ebe a, dị ka anyị na-ahụ, manganese, oxidized, na-emeghachi omume na chlorine na potassium salts nke ụmụ irighiri. The abụọ akụ mmeghachi omume na ọtụtụ-eji ụlọ ọrụ, ebe ọ bụ na endothermic potassium permanganate emepụta site na electrolysis nke uche.

The nkịtị Njirimara nke potassium permanganate

Na sayensị nke a compound na-akpọ potassium permanganate, nke bụ a granular kristal na orthorhombic ụdị ọchịchịrị-acha odo odo na agba. The potassium permanganate kristal ụdị erekasịchaala na kpo oku okpomọkụ nke 240 ° C na n'elu, na-akpụ oxygen evolushọn. Nke a na-egosipụta site na ndị na-esonụ omume:

2KMnO4 = K2MnO4 + MnO2 + O2.

The umi njupụta 2,703 g / CC. cube ezengwenri uka nke potassium permanganate - 158,03 g / mol. The solubility nke ogige ke mmiri na-adabere na ịta na mmiri okpomọkụ (data adade ke Isiokwu 1).
