Potassium oxide. Properties, mmepụta, ngwa

N'etiti chemical ọcha potassium pụta ìhè a ọnụ ọgụgụ nke ya pụrụ iche na ahụ na chemical Njirimara. N'ihi na chemists, ọ bụ nke mmasị n'ihi na ya elu ọrụ. Nke a ihe onwunwe e ozugbo meghachi omume na oxygen, kpo oku ikuku na-akpata ya ọkụ, ngwaahịa a mmeghachi omume na-aghọ potassium superoxide. Mmekọrịta na mmiri na acid ngwọta na-arụpụta a ngwa ngwa mgbanye na ọbụna gbawaranụ. Potassium bụ ike-agbake na igirigi ibu sulphuric acid na hydrogen sulfide, sọlfọ dioxide, na sọlfọ ahụ, nitric acid na-ebelata ka nitrogen oxides na molekụla nitrogen.

Na oge usoro na-ewe potassium na iri na iteghete na cell nọmba. Ọ bụ nke alkali ọla-akọwa silver-acha ọcha na agba na elu ductility a ihe onwunwe, ọ dị mfe bee na a mma ma na-egosi elu chemical ọrụ. Nke a na-akọwa eziokwu ahụ bụ na ọdịdị nke dị ọcha potassium adịghị ime. Otu n'ime ihe ndị bekee na nke potassium a gụnyere dị ka a constituent mmewere, ọtụtụ nkịtị bụ mmiri nke oké osimiri, ọ pụkwara ịhụ dị iche iche na mineral. The ọsọ nke ọxịdashọn nke a umi na-eduga ná eziokwu na potassium oxide (K2O usoro) ngwa ngwa na-agbanwe na steeti peroxide (K2O4).

Nweta potassium oxide nwere ike a metal site kpo oku 180 ° C na oxygen depleted gburugburu, ma ọ bụ site na kpo oku na a ngwakọta nke dara potassium superoxide. Dị ka akụkụ nke potassium oxide a hụrụ na ụfọdụ ụdị nke ciment na nri.

N'ihi na osisi potassium dị mkpa nke ukwuu, ọ bụ otu n'ime atọ bụ isi ụlọ ihe nke organic ogige, tinyere nitrogen na site. Na potassium larịị metụtara fruiting na ụdi ichebe mkpụrụ osisi na tubers. Potassium ekere òkè dị mkpa na njem nke sugar na guzobere nke akwukwo nri na ngwaahịa, nke a na-egosipụta na-abawanye nke starch na tubers, rhizomes na mgbọrọgwụ. Potassium nwere nti mmetụta na-amụba njupụta nke anụ ahụ nke na osisi, ha ị ga. Enweghị potassium-akpata na osisi bụghị ike n'ụzọ kwesịrị ekwesị banye nitrogen. Osisi na-eji nke potassium hydroxide. Ọ interacts na a dịgasị iche iche nke bekee na-enye nkịtị ọrụ nke osisi organism.

Enweghị potassium na ụfọdụ Ona na-ahụ ụgwọ atụrụ site na iji a dịgasị iche iche nke potash nri. Ha mmepụta a na dabere na ojiji nke eke ego nke potassium salts, minerals na-akpọ sylvinite na carnallite, a na igirigi ibu sulphuric acid potassium salts na-shenit Ken na langbeinite. Iji minerals na-enye a fatịlaịza na a elu ịta nke potassium.

The kasị fatịlaịza, nke na-agụnye a potassium oxide, a potassium nnu. Nke a ngwakọta na-finely ground ịnweta mejupụtara nke eke si sylvinite, na potassium chloride. potassium oxide bụ 40%.

The umi na ike isi Njirimara ike bụghị nanị na-eme ihe ike na asịd, acid oxides na ọbụna mmiri. A onwunwe nke a compound ka mgbanwe nke carbon dioxide na oxygen na ọtụtụ-eji gas masks egbochi ihe mmetụta ụkpụrụ na submarines. Poglotitetelem na nke a na-eme dị ka ihe equimolar ngwakọta nke sodium peroxide na potassium superoxide. N'ihe banyere ihe equimolar ngwakọta nke ngafe nke sodium peroxide etinye obi gị dum ọzọ gas karịa ya ekenyela. Mpịakọta abụọ nke carbon dioxide a tọhapụrụ onye oxygen olu. N'ihi ya na a bizi ohere mgbali dara. Ngafe potassium superoxide enye absorption mmetụta nke mpịakọta abụọ nke carbon dioxide na ntọhapụ nke atọ mpịakọta nke oxygen, nsogbu ahụ ga-ebili. Equimolar ichekwa nke ngwakọta oji akụkụ etinye obi gị dum na wepụtara, haruru.

Dị ka a ike oxidizing gị n'ụlọnga, peroxides na-eji na akwa ụlọ ọrụ maka bleaching nke akwa.
