Aluminum hydroxide

Ọdịdị aluminum hydroxide esonụ bekee. Dị ka a na-achị, ọ bụ a na-acha ọcha umi, gelatinous umu, ọ bụ ezie na e nwere ọdịiche na ọnụnọ nke a crystalline ma ọ bụ amorphous ala. Ihe atụ, na a mịrị amị ụdị, ọ crystallizes na-acha ọcha kristal nke bụ unyi anaghị agbasa na asịd audio ma alkalis.

Aluminum hydroxide nwere ike nyere na iwu crystalline ntụ ntụ nke na-acha ọcha na agba. Ime ọnụnọ nke pink na shades nke isi awọ.

The chemical usoro nke compound - Al (OH) 3. The onyinye nke alumina na mmiri na-etolite a hydroxide nke aluminum, chemical Njirimara nke na-na-n'ụzọ dị ukwuu kpebisiri ike site ọcha ke ya mejupụtara. Nke a compound na-akwado ya site na omume ihe aluminum nnu na itughari alkali na na mmekọrịta, si otú ọ dị mkpa iji gbochie ha overabundance. Nwetara n'oge mmeghachi omume nke aluminum hydroxide ịkpali nwere ike mgbe ahụ ga-meghachi omume na acid.

Aluminum hydroxide na-meghachi omume na otu okenye ihe ngwọta nke rubidium hydroxide, ihe alloy nke na umi, cesium hydroxide, cesium carbonate. N'ọnọdụ nile, ndị mmiri na-tọhapụrụ.

Aluminum hydroxide nwere a molekụla ibu hà 78,00, fọrọ unyi anaghị agbasa na mmiri. umi njupụta bụ 3,97 g / cm3. N'ịbụ amphoteric, aluminum hydroxide na-meghachi omume na acid, nke, na a na-ajụ-enwetara site na yiri Jeremaya mere na mmiri nnu a tọhapụrụ. N'elu ntinye n'ime mmeghachi omume na alkalis apụta mgbagwoju salts - gidroksoalyuminaty, e.g., K [Al (OH) 4 (H2O) 2]. Metaaluminate kpụrụ mgbe aluminum hydroxide gwakọtara ya anhydrous alkalies.

Dị ka ihe niile amphoteric bekee, acidic na isi Njirimara nke ma aluminum hydroxide egosi site mmeghachi omume na ike asịd na alkalis. Na ndị a Jeremaya mere mgbe etisasịwo ke asịd hydroxide cleaves na ion nke hydroxide, na na mmekọrịta ya na alkali - rapara hydrogen ion. Iji hụ na nke a, ọ bụ omume, n'ihi na ihe atụ, iji duru mmeghachi omume, nke na-agụnye aluminum hydroxide, sodium hydroxide. Ọ dị mkpa na-akpa àgwà a rijuru afọ tube bit aluminum sawdust na wụsa a obere ego nke sodium hydroxide adịghị aka 3 milliliters. The tube a ga-emechi tightly stoppered, na-amalite a ngwa ngwa kpo oku. Mgbe nke ahụ gasịrị, ndị tripod gwara tube, ọ dị mkpa na-anakọta hydrogen raara nye ọzọ tube, na-etinye ya na a tupu capillary ngwaọrụ. Mgbe ihe otu nkeji vial ga-ewepụ si capillary na iwebata ire ọkụ. Ọ bụrụ na ndị na vitro kpọkọtara ọcha hydrogen - ọkụ ga-ebe na-eji nwayọọ, na otu ikpe, ma ọ bụrụ na ọ bụ ikuku - ga-akụ.

Aluminum hydroxide kwadebere na laabu na ọtụtụ ụzọ:

- by imeghachi omume aluminum salts na alkaline ngwọta;

- decomposition usoro nke aluminum nitride n'okpuru nduzi nke mmiri;

- carbon site agafe a pụrụ iche hydro nwere Al (OH) 4;

- mmetụta nke amonia na alumina hydrate nnu.

The ulo oru mmepụta bụ n'ihi na nhazi nke bauxite. Eji dị ka mmetụta technology aluminate ngwọta carbonates.

Aluminum hydroxide na-etinyere ke imewe nke fatịlaịza, cryolite, a dịgasị iche iche nke ọgwụ na ahụ ike na-emepụta ọgwụ na ngwaahịa. Na chemical n'ichepụta ihe onwunwe na-eji maka nkwadebe nke aluminum Fluoride na sọlfọ ahụ. Oké Mkpa compound ke imewe nke akwụkwọ, plastik, akọwa na ọtụtụ ndị ọzọ.

The ọgwụ na-eji n'ihi na mmetụta dị mma nke preparations nwere n'ọrụ mmewere na ọgwụgwọ nke gastric ọrịa, hyperacidity ahụ peptic ọrịa.

Mgbe ejizi umi, kwesịrị lezie anya nke inhalation nke vapors, dị ka ha ka oké akpa ume mebiri. N'ịbụ slabodeystvuyuschim laxative, ọ dị ize ndụ na nnukwu doses. Mgbe aluminosis akpata corrosion.

The umi ya onwe ya bụ ala-ezu, n'ihi na ọ dịghị eme na oxidants.
