Pehea e hoomakaukau i koʻana koko pāʻoihana o ferric koloriside

Iron koloriside (III) ma ka pāʻoihana ka mea eleele waihoʻoluʻu hiki ke hoomakaukau i loko o ke keʻena hoʻokolohua a ma ka hale. Koi wela-hoʻopale ole-mea hao cookware a me ka maemae wela ka wai (hoolapalapaia paha i puhi ia). Ma hope o mea hoʻoheheʻeʻia a me ka maluhia iho la huli pouli eleele wai. Aia nō i ka helu o nā hiʻona o ka makaukau o ferric koloriside pāʻoihana, a e ike mua e hoʻomaka ana i ka hana ana me ia.

ferric koloriside

Anhydrous ferric koloriside, ua hanaʻia ma ka Nine Inch hana - FeCl ₃ - nā pōaka pouli eleele me ka malu o kaʻulaʻula, he poni, pouli'ōmaʻomaʻo. Molar kaupaona - 162,21 g. / Mol. Waiwai heheʻe i ka wela o ka 307,5 ° C, a me 500 ° C hoʻomaka e decompose. I ka 100 g. O ka wai mea hoʻoheheʻe kaupaona anhydrous paʻakai:

• 74,4 g. (0 ° C);
• 99 g. (25 ° C);
• 315 g. (50 ° C);
• 536 g. (100 ° C).

Anhydrous ferric koloriside (III) - loa hygroscopic waiwai hoʻomaka koke,ʻo ona mau, mai ka puni kaiapuni. Ma ka lewa reacts me ka wai haliu ae la ia i loko o yellow nā pōaka hexahydrate FeCl ₃ + 6H ₂ O. _ka nui hapa iki o anhydrous ferric koloriside ma ka waiwai, loaa i kalepa, ka mea hiki 95%. Aia He He uuku ka nui o ferrous koloriside FeCl ₂ a me insoluble impurities. ʻIliahi He inoa - "Ferric koloriside." I ka waiwai o ke ahi a me ka Naita me ia, akā, kona kākoʻo pāʻoihana i ka corrosive ia ma luna o ka mea hiki ke hooheheeia mea.

Ferric koloriside hexahydrate (III)

Eia kekahi hana produces anhydrous mea pōaka nuipa hapa ferric maloko (III) o 60%. I ka waiwai a pau o ka apana o ka mea hookahi hue yellow-eleele mea pōaka nuipa a wehe. An pono o ka Ion, a ferric hao - waihoʻoluʻu. No ka mea degere o ka'okesaside o Fe ²⁺ mea ano he omaomao iki, hydrated ferric koloriside hexahydrate - uliuli-uliuli paa. Ke'okesaside Fe ³⁺ Ion kuai kala mai yellow i ka mea eleele. No ka qualitative hoʻoholo i loko o ferric koloriside pāʻoihana e reagents:

• NaOH (ikeia eleele precipitate Fe (OH) _3);
• K ₄ [Fe (CN) _6] (precipitate i Konakele. KFe [Fe (CN) _6], uliuli);
• KCNS, NaCNS (ferric thiocyanate hana Fe (CNS) ₃ ulaula).

Like dilute ferric koloriside

ka hao (III) koloriside like me ka mea eleele a ulaula kala like 'ole o ka pāʻoihana hiki ke loaʻa i loko o ka oihana ka mea ulana pukapuka, i hoomakaukauia ma ka keʻena hoʻokolohua a ma ka hale. Ma ka hope hihia, pono koi wela-hoʻopale ole-mea hao pahu waihona (aniani, ea, pālolo). Ka wai, e hoike mai i ka paakai hiki ke lawe mai i ka piula wai. Maluhia o ka Lehulehu - hoolapalapaia paha i puhi ia. Wela i 50-70 ° C ka wai i waiho i loko o ka ipu, a laila, ninini iho la i ka poe liilii,'āpana waiwai. Ka huliāmahi o ferric koloriside a me ka wai - 1: 3. Ka wā hoʻomākaukau i kekahi pāʻoihana o ka mea pōaka, laila ka wai ua koi 'emi, no ka mea, ua hookomoia ma ka mea pōaka hydrate (40% ma ke kaupaonaʻana). Waiwai ua hou a hiki i ka pāʻoihana iki ma ka liʻiliʻi, kēlā i malamaʻi, - ma kahi 5-10 g. Koke ninini i ka hitch holoʻokoʻa ua i waiho no i ka kokololio ano o ka hydration naoh. Oe hiki ole hoʻohana metala mau ipu (puna, spatulas). Ka paʻakai E e loa ia ka pono i ka mehana ka wai e a na nā pōaka e e pono kawili pu ia me ka wai. Ua hōʻeleu i ka hou o hydrochloricʻakika (1/10 ma ke kaupaonaʻana, o nā nā pōaka). Ma hope o ku ana no kekahi mau hora ma ka lalo o ka precipitate kānāwai ma muli o ia i ke alo i loko o ka ho'āʻo kuleana a me ke kahua o ka hao hydroxide i ka naoh. Ua Ua wae 'kumukūʻai pāʻoihana ka pouli eleele, a waiho i loko o ka sila ea ipu ma ka lōpū ana wela a me ka wa e kaawale aku o ka pololei Map.

Ka hoʻohana a ferric koloriside a me ka hanalimaʻaha hui uila. wahi lulu ana

Me ka hao paʻakai i hoʻohana 'ia ma na kula. trivalent metala koloriside ua hoʻohana 'ia no ka lapaʻau o ka wai, ke hooheheeia, a me ka hoʻopunipuni ka inika. Ka waiwai hoʻohana ma ka hanalima ke aloha hoʻololi kemikala (hōʻeleu, oxidant). Pakahi aku la ia iʻimi ai ma hope o coagulating waiwai ion Fe ³⁺ ma o ka huikala ana o ka kulanakauhale a me ka hanalima effluents. Ma lalo o ka hana o ka ferric koloriside ke olonā i insoluble (particles) coalesce a precipitate impurities. Kekahi hapa o ka paa o ka wailana contaminants i wehe 'ia ma ka wastewater lapaau mea kanu. Ka mea pōaka a anhydrous paakai FeCl ₃ e hoʻohana 'ia i loko o ka keʻano o ka hanaʻana o etching metala papa. Waiwai ua hou a hiki i ka pōhaku puna i ka hoʻohuiʻana paha i kona ikaika.

Nineʻike manaʻo i loko o ka etching huakai kaapuni papa. maluhia ana

Popular Nine Inch waiwai no ka etching i paiia kaapuni papa - ferric koloriside. A pāʻoihana no keia mea ua hoomakaukauia mai 0,150 kg o ka paakai a me 0,200 hano o mehana ka wai. Ua loaʻa ka Ion Fe ^3+, Cl ^-, a me ka hui i hanaʻia ma ka hydrolysis eleele - ferric hydroxide. Ke kaʻina loaa e like me ke ano: FeCl ₃ + 3HOH↔ Fe (OH) ₃ ⁺ 3Cl ^- + 3H +. Ke keakea o ka mea hoʻohaumia o ka papa naoh he hopena ia i complicate hou etching. Salt iho - he pili-e yiaeaiiacaaeneiie waiwai, akā, i loko o ke kaʻina hana o ka AaOIeIOUIeXAOAaIN me ka wai ke hookuu aku oia corrosive ohu. Ka hana e halihaliia oia iwaho o ka wehe ea paha i loko o ka luawai-ventilated wahi kaawale no koe. Leka i ka pāʻoihana a hiki i kaʻili a me ka mucous membranes kūpono i ka mea ukiuki loa, a hiki i dermatitis. He mea pono e hoʻohana pilikino aiiay? Ieaoa (goggles, Loan). I hui 'ana me ka caustic pāʻoihana mea pono e holoi i ka ili me ka nui o ka wai.
