Iron hydroxide 3

Ke'okanikaʻole i huiia ka mea hao hydroxide 3 i ka Nine Inch haʻilula Fe (OH) 2. Ua lilo i ka moʻo o amphoteric i huiʻia o ka hao, a i Kīwala'ō ma lalo o ka waiwai i mea typical kumu. Ma nānaina o keia i ka waiwai o ke keʻokeʻo nā pōaka i ka wā hooloihiia waiū i na ke ao o waho i nā poeleele hoi. Aia mau Lolina o he omaomao iki nā pōaka. I ka maʻamau o ke ola mau waiwai ke mālama kēlā me kēia i loko o ka palapala o ka omaomao iki hoʻokomo kālā ma luna o ka mea hiki ke hooheheeia surfaces, i Hōʻike i ka hoʻomaka 'ana o ke kaʻina hana ka popo - hao hydroxide 3 lawelawe' ana me kekahi o na kuʻina waena o ke kaʻina.

Ke ano o ka hui e like amakinita. Kēia mea pōaka mea pōhaku, ma ke kaʻawale hao he oi impurities o makanekiuma a me ka manganese, a pau o kēia mau waiwai haawi amakinitu okoa malu - mai yellow-uliuli a pau, e pale uliuli, ke kaumaha ma muli o ka pakeneka o ka ua hehee ai. Ka paakiki o ka mea pōhaku mea 3.5-4 ma ka Mohs pālākiō huahelu, a me ka pa apŘ o ma kahi o 3 g. / Cm³.

Ke physical waiwai o ka waiwai e kekahi loaʻa kona loa haʻahaʻa solubility. Ma ka hihia ma ka hao hydroxide 3 ua enaena, ka mea, ua decomposed.

Kēia waiwai He loaʻeleu a me ka hana a me na mea he nui nā waiwai a me ka hui. Ke'ōlelo mai, no ka mea hoike, me ka waiwai o ka waihona ipu, e komo i ka neutralization naoh me ka okoa nāʻakika. Ma kekahi, sulfuricʻakika, ferric hydroxide 3 ma reactions alakai ai i ka? Iecaianoaaiiie o ka hao sulufahate (III). No keia naoh hiki'ākoʻakoʻa ma kaʻike mau calcination i wehe lewa, e like me ka inexpensive iaoia o ka hana ua ia sulphate nā ma keʻena hoʻokolohua, a me ka hanalima hana kūpono.

Iloko o ka naoh me hydrochloricʻakika, kona hopena o ke kahua o ka hao koloriside (II).

Ma kekahi mau hihia, hao hydroxide a me 3 i ho'āʻoʻakika waiwai. Ke'ōlelo mai, no ka laʻana, ma ka reacting me ka lahui i kia (lehulehu e ia ma ka liʻiliʻi 50%) paʻakai hydroxide pāʻoihana ua loaa tetragidroksoferrat (II) paʻakai e precipitate like me ka. Eia naʻe, no ke kahe ana o ia ka naoh mea pono ia i ke 'ano pilikia rula: ka naoh e mākaukau kaua i loko o ka pāʻoihana hoolapalapa ma lalo o ka naikokene ka lewa kaiapuni.

E like me ua oleloia, ma ka paio hahana maoli nō ka waiwai decomposes. I ka hopena o keia? Anoe? Aiey hana like hao'okesaside (II), a, ma ka hou, e like me impurities mea hao hao loaa a me kona nā mea loaʻa dizheleza'okesaside (III), Nine Inch haʻilula o Fe3O4.

Pehea e paka hao hydroxide 3, o ka wa hoomakaukau ia no i ua pili i kona hiki e pane koke me nāʻakika? e hoomau aku i ka hoʻokolohua ma mua, eʻoiaʻiʻo, e hoʻomaopopo i ka palekana rula ka wā e mālama nei i ka ho okolohua. Mau lula pili i na hihia a pau, i ka iapaau ana oʻakika-'ākilikai pāʻoihana. Nui 'aneʻi - e hōʻike i ike loea hoomalu a me ke pale aku ingress pāʻoihana droplets ma luna o kaʻili a me ka mucous membranes.

Penei, i kekahi ke loaa hydroxide i ka naoh i loko i ka hoʻolauna hao koloriside (III) a me KOH - potasiuma hydroxide. Kēia iaoia - ka loa, he pono ole ke kumu no ka ho okumu ana o insoluble. Ma ka naoh o kēia mau waiwai puka maiʻike mau mail naoh, kūpono ma ka precipitate huli mea eleele. Kēia precipitate o ka makemake waiwai.

Ka hoʻohana o ka hao hydroxide ma ka hanalima? Iecaianoaaiiie i ke kaiāulu. Ka loa, he pono ole o kona hoʻohana likeʻeleu waiwai i loko o ka nikala-hao o na pu ki type. A, i ka hui hoʻohana i metallurgy e paka na ferro oka a pau, e like me ka pono me ia ma ka electroforming prizvodstvo, avomobilestroenii.
