Umutungo wumubiri

Phe ya chimique ya silver oxyde ni Ag2O, ifite uburemere bwa 231.74.Umukara wijimye cyangwa umukara wijimye, ufite ubucucike bwa 7.143g / cm, wangirika vuba gukora ifeza na ogisijeni kuri 300 ℃.Gushonga buhoro mumazi, gushonga cyane muri acide ya nitric, ammonia, sodium thiosulfate, hamwe na potasiyumu cyanide yumuti.Iyo igisubizo cya ammonia cyakoreshejwe, kigomba kuvurwa mugihe gikwiye.Kumara igihe kinini bishobora kugusha kristu yumukara iturika cyane - nitride ya silver cyangwa silver sulfite.Ikoreshwa nka okiside hamwe nibirahure.Byateguwe mugukora igisubizo cya nitrate ya silver hamwe na sodium hydroxide.

Brown cubic kristaline cyangwa ifu yumukara.Uburebure bwa Bond (Ag O) 205pm.Kwangirika kuri dogere 250, kurekura ogisijeni.Ubucucike 7.220g / cm3 (dogere 25).Umucyo ubora buhoro buhoro.Kora hamwe na acide sulfurike kugirango ubyare sulfate.Gushonga buhoro mumazi.Gushonga mumazi ya ammonia, sodium hydroxide yumuti, kugabanya aside nitric, hamwe na sodium thiosulfate.Kudashonga muri Ethanol.Byateguwe mugukora igisubizo cya nitrate ya silver hamwe na sodium hydroxide.Wet Ag2O ikoreshwa nkumusemburo mugihe usimbuye halogene hamwe nitsinda rya hydroxyl muri synthesis organique.Ikoreshwa kandi nkibikoresho byo kubika no gukoresha ibikoresho bya elegitoroniki.

 

Umutungo wimiti

Ongeramo igisubizo caustic kumuti wa nitrate ya silver kugirango ubone.Ubwa mbere, haboneka igisubizo cya hydroxide ya silver na nitrate, kandi hydroxide ya silver ibora mo okiside ya feza namazi mubushyuhe bwicyumba.Okiside ya silver itangira kubora iyo ishyutswe kuri 250 ℃, ikarekura ogisijeni, kandi ikangirika vuba hejuru ya 300 ℃.Gushonga buhoro mumazi, ariko bigashonga cyane mubisubizo nka acide nitric, ammonia, potasiyumu cyanide, na sodium thiosulfate.Nyuma yo kumara igihe kinini kumuti wacyo wa ammonia, kirisiti yumukara iturika irashobora rimwe na rimwe kugwa - birashoboka ko nitride ya silver cyangwa iminide ya silver.Muri synthesis organique, amatsinda ya hydroxyl akoreshwa mugusimbuza halogene cyangwa nka okiside.Irashobora kandi gukoreshwa nkibara ryinganda zikora ibirahure.

 

Uburyo bwo kwitegura

Okiside ya silver irashobora kuboneka mugukora hydroxide ya alkali hamwe na nitrate ya silver.[1] Igisubizo kibanza kubyara hydroxide ya silver idahindagurika cyane, ihita ibora kugirango ibone amazi na oxyde ya silver.Nyuma yo koza imvura, igomba gukama munsi ya 85 ° C, ariko biragoye cyane kuvana amazi make muri oxyde ya feza amaherezo kuko uko ubushyuhe bwiyongera, oxyde ya silver izabora.2 Ag + + 2 OH− → 2 AgOH → Ag2O + H2O.

 

Ikoreshwa ryibanze

Ahanini ikoreshwa nkumusemburo wa synthesis.Ikoreshwa kandi nk'ibikoresho byo kubungabunga, ibikoresho bya elegitoroniki, ibara ry'ikirahure, hamwe no gusya.Ikoreshwa mubikorwa byubuvuzi kandi nkibikoresho byogeza ibirahuri, amabara, hamwe nogusukura amazi;Byakoreshejwe nkibikoresho byo gusiga no gusiga amabara kubirahure.

 

Ingano yo gusaba

Ifeza ya silver ni ibikoresho bya electrode ya bateri ya silver.Ni na okiside idakomeye kandi ifite intege nke muri synthesis organique, ishobora kwitwara hamwe na 1,3-imyunyu ngugu ya imidazole hamwe nu munyu wa benzimidazole kugirango ubyare azene.Irashobora gusimbuza ligande idahindagurika nka cyclooctadiene cyangwa acetonitrile nka reagent yohereza karbene kugirango ihuze ibyuma bya karbene byinzibacyuho.Byongeye kandi, okiside ya silver irashobora guhindura bromide kama na chloride muri alcool mubushyuhe buke kandi imbere yumwuka wamazi.Ikoreshwa ifatanije na iodomethane nka methylation reagent yo gusesengura isukari methylation hamwe no gukuraho Hoffman, ndetse no okiside ya aldehydes kuri acide karubasi.
