Potasiuma permanganate: nui Nine Inch ka waiwai a me ka naoh

Potasiuma permanganate ma Roma ua kapaia Kalii permanganas. Ke ao nei, Ua pono ka potasiuma permanganate - potasiuma ka paʻakai i loko o ka naoh o manganeseʻakika. Lettering KMnO. Hoʻokaʻaʻike me ke aloha ano o ka kumuʻiʻo - albuminates, kino ka waiʻona ma ke ana ma keia naoh ua maalo ae ke ahi ka waiʻona ma, knitting, kūloko mea ukiuki loa, oiai ka i hoola ai, a deodorant waiwai a me ka antidote.

Potasiuma permanganate i hoomakaukauia e electrochemical'okesaside o manganese i huiʻia ai ma ka hoololi ana i kā lākou mau huliāmahi. Eia nō kekahi reactions e potasiuma permanganate, ua hoʻomano hoʻohana 'ia ma ka hana a me ka pharmacology:

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

2K2MnO4 + 2H2O → 2KMnO4 + h2 ↑ + 2KOH.

Maanei, e like me kakou e ike nei, manganese, oxidized, ua reacted me ka chlorine a me ka potasiuma paʻakai o nā lātoma. Ka lua o ka puʻu e kū pono naoh ua hoʻomano hoʻohana 'ia ma ka hana, no ka mea, endothermic potasiuma permanganate hua mai la ma ka electrolysis o ke kiaʻana i kāna.

Ke physical waiwai o ka potasiuma permanganate

Ma ka 'epekema o keia hui ua i kapa potasiuma permanganate, i mea he granular nā pōaka a me orthorhombic ano o ka pouli poni ano. Ke potasiuma permanganate nā pōaka palapala decomposes ma paio hahana maoli nō mahana o ka 240 ° C a me luna, ho okumu i ka oxygen evolution. Keia ua kakaʻikahi e ke kēia naoh:

2KMnO4 = K2MnO4 + MnO2 + O2.

Ka waiwai pa apŘ 2,703 g. / CC. kupa molar nuipa o potasiuma permanganate - 158,03 g. / Mol. Ke solubility o ka hui i loko o ka wai ma luna o hilinaʻi nui o ka lehulehu, a me ka wai mahana (ʻikepili hōʻike ma ka Papa 1).

Papa 1. Solubility o potasiuma permanganate ma kekahi mau Mahana O Ke Kai

Ke kaumaha ma muli o ka nui o na nā pōaka i hoʻohuiʻia i ka wai o kekahi ana wela, kēlā pāʻoihana e i ka hue - mai ka nawaliwali, pale magenta ma ka haʻahaʻa lehulehu i ka poni-lila - ma nui. Other nā'uheheʻe potasiuma permanganate nā pōaka nei iluna acetone, ammonia a me ka meto ka waiʻona.

Nine waiwai o ka potasiuma permanganate

Waiwai "potasiuma permanganate" He 'ano ikaika o oxidizing hope paha. Ke kaumaha ma muli o ka pH o ka meakino e hana ma luna o acee? Iuo oeiia o ka waiwai i hoemiia e manganese ma ka helu kaulike i huiʻia o kekahi mau degere o ka'okesaside. No ka laʻana, i loko o kaʻakika 'ia - II, i loko o ka kona'ākilikai - i VI, ma ka'ākilikai nā meakino, niioaaonoaaiii - i ka IV.

E pili ana i ka noʻonoʻo sulfuricʻakika, potasiuma permanganate, Nine Inch ka waiwai i hoike'okesaside ke kumu no ka pahū naoh, a hookuu aku oia i oxygen ma ka wā wela - kēia papa hana ua hoʻomano hoʻohana O2? Iecaianoaaiiuo ma ka hana.

Ka hoʻohana o potasiuma permanganate

Ma kēia keʻena hoʻokolohua? Iecaianoaaiiuo o potasiuma permanganate māhele i loko o ke aloha hoʻololi kemikala like me ka oxidant. Ke'ākilikai pāʻoihana mea mana i loko o ka hoʻomaʻemaʻeʻana a me ka degreasing hope paha. Popular a versatile palapala noi o 0,1% pāʻoihana ma ka lapaau ana i ka iapaau ana o'ā, holoiʻia ia, disinfection, Napuelua toxins. Kekahi keʻena kūʻai lāʻau lapaʻau mai e keia mea, mai ka mea o ke Kuhina, ka mea, ua hoʻolaha i ka Naita me p ÷ ino. Akā, e hiki ke loaa potasiuma permanganate i loko o ka mahiʻai mala hale kūʻai ma ka mea, ua kūʻai liloʻia aku me he mea hoʻomomona.
