Hydroxide aluminium

Ponahalo e aluminium hydroxide latelang dintho. E le busa, ho ke ke ntho e tšoeu, mefuta gelatinous, le hoja ho na le mekete e fapaneng ka ho ba teng ha e bonaletsang kapa boemo amorphous. Ka mohlala, ka mofuta o omisitsoeng, ho hlaka ka ho benyang ka kristale tšoeu tse insoluble ka acid mamelwang kapa alkalis.

Aluminium hydroxide ka fuwa le o motle bonaletsang phofo ea 'mala o mosoeu. Lumeletsoe ho ba teng ha ea pinki le shades ea bohlooho.

The lik'hemik'hale moralo oa ho kompone - Al (OH) 3. The komponeng ea ea alumina le metsi theha hydroxide ya aluminium, lik'hemik'hale thepa tse hape haholo e behilweng ke thepa ea motheo e ka sebopeho lona. komponeng ena e lokiselitsoeng ke itšoara e aluminium letsoai le hlapolla alkali le sebelisana, ka tsela eo e ke ho hlokahala hore ho thibela overabundance bona. O ile a fumana ka nako ya itsoara joang ka ea aluminium hydroxide precipitate ka ka nako eo ho o ile a etsa'ng ka acid e ea.

hydroxide aluminium e ileng a itšoara ka tharollo ea metsi ya rubidium hydroxide, e motsoako ea ntho eo, cesium hydroxide, cesium carbonate. Maemong ohle, metsi e lokolloa.

Aluminium hydroxide na le boima ba 'mele ea limolek'hule lekanang 78,00, hoo e batlang e insoluble ka metsing. ntho segokanyipalo ke 3,97 g, / cm3. Ho amphoteric, aluminium hydroxide e ileng a itšoara ka acid e ea, moo, ka seaplane fumanoa ka liphetoho tse tšoanang le metsi le letsoai e lokolloa. Holim 'a ho kena ba itšoara joang le alkalis hlaha rarahaneng letsoai - gidroksoalyuminaty, mohlala, K [Al (OH) 4 (H2O) 2]. Metaaluminate thehoa ha aluminium hydroxide fused le alkalies anhydrous.

Joaloka lintho tsohle amphoteric, asiti le motheo thepa ea bobeli e bontša hydroxide aluminium ke itsoara joang ka acid matla le alkalis. Ka liphetoho tsena ha qhalwa ho ya ka acid hydroxide cleaves le ions tsa hydroxide, 'me sebelisana le a alkali - khomaretse Ion hydrogen. Ho bona sena, ho ka etsahala, ho etsa mohlala, ho khanna ba itšoara joang, e leng ho akarelletsa ho hydroxide aluminium, hydroxide sodium. Hoa hlokahala ho khannela ba tlatse tube, hanyane aluminium sawdust le tšela e nyenyane ea hydroxide sodium ha le leholo ho 3 dimililitha. Tube lokela ho koaloa ka thata-thata stoppered, 'me ba qala ka futhumatsang lieha. Ka mor'a moo, tripod lokisa sepeiti tube,, ho ke ke ho hlokahala hore ho bokella hydrogen inehetseng ho tube, 'ngoe, ho beha holim' a sesebediswa pele ho capillary. Ka mor'a hoo e ka bang motsotso o le vial lokela ho tlosoa tloha capillary le ho tlisa lelakabe. Haeba ka vitro bokane hydrogen e hloekileng - o tukang o tla nka sebaka ka lenyele, haeba ho le joalo, haeba ho ke ke moea - tla opa.

Aluminium hydroxide lokiseditsweng ho laboratori ka litsela tse ngata:

- ka itšoara letsoai aluminium le tharollo alkaline;

- li bole kapele 'mokhoa oa nitride aluminium le tlas'a tšusumetso ea metsi;

- k'habone ka ho fetisa ka haeterojene khethehileng e nang le Al (OH) 4;

- liphello tsa ammonia pele ea alumina hydrate letsoai.

Tlhahiso indasteri e loketseng ho sebetsa bauxite. Sebelisoa e le tshusumetso thekenoloji aluminate ditharollo carbonates.

Aluminium hydroxide e sebelisoa ka tlhahisong ea menontsha, cryolite, mefuta e fapaneng ya bongaka le meriana lihlahisoa. Boitsebisong lik'hemik'hale difeme sebediswa bakeng sa ba lokisetsa ho ea fluoride aluminium le sebabole. Bohlokoahali komponeng ka tlhahisong ea pampiri, dipolasetiki, pente le ba bang ba bangata.

tšebeliso ea bongaka e loketseng ho tšusumetso e ntle ea ka litokisetso tse nang le karolo ea mafolofolo ho phekola mafu a ho gastric, hyperacidity 'mele peptic mafu.

Ha sebetsana ntho e, lokela ho ba hlokolosi ka ho inhalation tsa mouoane, ha ba ntse ba bakela haholo matšoafo senya. Ho laxative slabodeystvuyuschim, ho ke ke kotsi ka tekanyetso kgolo. Ha aluminosis bakang ts'enyeho.

Ntho ka boeona e ke tsela e sireletsehileng ka ho lekaneng, hobane ha e itšoara joang le oxidants.
