Hydroxide aluminium

Imaansho hydroxide aluminium socda walxaha. Sida caadiga ah, waa walax cad, noocyada gelatinous, in kastoo ay jiraan kala duwanaansho ay goobjoog ka ahaayeen crystalline ama gobolka qaab ma lahayn. Tusaale ahaan, foomka la qalajiyey, waxa crystallizes in kiristaalo cad kuwaas oo beelaya in acids audio mana alkalis.

hydroxide Aluminum waxaa lagu bixin karaa iyo budada crystalline wanaagsan ee midabka cad. joogitaanka oggol yahay ee pink iyo hooska cawlan.

formula The kiimikada ee xarunta - Al (OH) 3. xarunta of alumina iyo biyo u sameeyaan hydroxide ah ee aluminium, guryaha kiimikada kuwaas oo sidoo kale inta badan ay ka wada qayb ee ay ka kooban. Xarunta Tani waxaa loo diyaariyey by ficil cusbo aluminium la alkali milo iyo isdhexgal, sidaas waxaa lagama maarmaan ah si looga hortago in ay badin. Helay inta lagu guda jiro falcelinta ee soo dadajin hydroxide aluminium ka dibna la jawaabay karaa acid ah.

hydroxide Aluminum waxaa ka jawaabay xal aqueous of hydroxide rubidium, waxaaga ah oo ah walaxda in, hydroxide cesium, carbonate cesium. Xaaladaha oo dhan, biyaha la sii daayay.

hydroxide Aluminum leeyahay miisaanka kelli loo siman yahay 78,00, ficil ahaan beelaya biyo. cufnaanta walaxda waa 3,97 g / cm3. In amphoteric, hydroxide aluminium waxaa ka jawaabay acid ah, kuna waari dhexdeeda, in dhexdhexaad ah helay dareen diidmo oo la mid ah oo biyo cusbo la sii daayay. Marka galay falcelinta la alkalis entry muuqan cusbada adag - gidroksoalyuminaty, tus, K [Al (OH) 4 (H2O) 2]. Metaaluminate sameeyay markii hydroxide aluminium dhisnayd la alkalies ammooniya.

Sida dhammaan walxaha amphoteric, guryaha acidic iyo aasaasiga ah ee labada shows hydroxide aluminium by reaction la acids xoog iyo alkalis. In celintan oo markii diri ee acids Cuskada hydroxide ka udhigo of hydroxide ah, iyo in la dhexgalo oo la alkali ah - dhegay ra'iyi hydrogen. Si arrintan loo arki, waxaa suurtagal ah, tusaale ahaan, si ay u qabtaan falcelinta, kaas oo ku lug leedahay hydroxide aluminium, hydroxide sodium. loo baahan yahay si ay u qabtaan tube ka dheregtaan balka aluminium yara iyo ku shub qadar yar oo ah sodium hydroxide kama weyna 3 millilitir. tube waa in la xiraa si adag stoppered, oo uu bilaabo kululaynta la'ahay. Intaas ka dib, tube qamaar Maala ah, waxaa lagama maarmaan ah si ay u ururiyaan hydrogen ka go'an in tube kale, gashan on qalab pre-gaddoonka ah. oo ku saabsan hal daqiiqo ka dib weelka waa in laga saaro gaddoonka ah iyo in ay keenaan ololkii. Haddii giisa soo ururay hydrogen saafi ah - gubashadii dhici doona aamusnaan, in kiiska la mid ah, haddii ay tahay hawada - sacbin doonaan.

hydroxide Aluminum diyaariyey shaybaarka siyaabo dhowr ah:

- by ficil cusbada aluminium iyo xal xumadoodu;

- Habka kala daatay ee nitride aluminium sarkhaansan oo biyo ah,

- carbon by marayay hydro gaar ah oo ay ku jiraan Al (OH) 4;

- saamaynta ammonia on cusbo hydrate alumina.

wax soo saarka warshadaha waxaa sabab u ah howsha bauxite. Waxaa loo adeegsaday sida saamaynta technology xal aluminate carbonates.

hydroxide Aluminum waxaa laga codsadaa in soo saaridda of Bacriminta, cryolite, noocyo kala duwan oo soo saarka caafimaadka iyo dawooyinka. In wax soo saarka kiimikada loo isticmaalo diyaarinta fluoride aluminium iyo baaruud. xarunta maarmaan in soo saaridda of warqad, bacyaal, rinjiga iyo kuwo kale oo badan.

isticmaalka caafimaad ayaa ay sabab u tahay saamaynta wanaagsan ee diyaarinta ka kooban element firfircoon ee daaweynta ee cudurada gastric, jirka hyperacidity cudurada ulcer.

Marka walaxda, iska jira waa in ka mid ah neefsasho ah uumi, maadaama ay dhibaato u geystaan sanbabada daran. In caloosha jilcisa slabodeystvuyuschim, waa halis in qiyaasood oo waaweyn. Marka aluminosis sababa daxalka.

walax laftiisa waa ammaan ku filan, sababtoo ah ma aysan ka fal la oxidants.
