Indlela ukulungiselela isixazululo aqueous of chloride ferric

Iron chloride (III) e isixazululo umbala onsundu ingalungiswa endaweni yokucwaninga noma ekhaya. Dinga ukushisa ukumelana non-metallic Cookware futhi ahlanzekile ashisayo amanzi (abilisiwe noma distilled). Ngemva Ukuqedwa futhi sokulungisa jika mnyama uketshezi onsundu. Kunezindlela eziningana izici ukulungiswa isixazululo chloride ferric, okumele ukwazi ngaphambi kokuqala umsebenzi naye.

chloride ferric

Anhydrous chloride ferric, oluqanjwe embonini chemical - FeCl ₃ - zinhlayiya konsundu ngenxa yemibala yawo ebomvu, onsomi, oluhlaza amnyama. isisindo izinyo lomhlathi - 162,21 g / Mol. Into liyancibilika ezingeni lokushisa 307,5 ° C, nge 500 ° C iqala ukubola. Ngo 100 g ancibilikile kuhlaziywe usawoti anhydrous:

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

Anhydrous chloride ferric (III) - izidakamizwa hygroscopic kakhulu edonsela ngokushesha umswakama ezungezile. Emoyeni ihlangana emanzini kuphenduke zinhlayiya ophuzi hexahydrate FeCl ₃ + 6H ₂ O. _Ingxenyana mass anhydrous chloride ferric ngoqobo, labawatfolile esifundvweni nobe commerce, ifinyelela 95%. Kukhona inani elincane chloride ayoni FeCl ₂ futhi ukungcola zingaxazululeki. igama Trade - "chloride Ferric." Ingqikithi umlilo kanye nokuqhuma, kodwa ikhambi layo inomphumela ezonakalisayo phezu izinto eziyinsimbi.

Ferric chloride hexahydrate (III)

Ngaphezu kwalokho umkhakha ukhiqiza crystalline anhydrous mass ingxenyenamba ferric therein (III) 60%. Ingqikithi kuyinto mass crystalline ophuzi onsundu noma izingcezu okubi lokhu kwenza umbala obomvana efanayo. Isici esibalulekile salo athomu nensimbi ferric - umbala. Ukuze degree of namachibi of Fe ²⁺ sici ogqamile, amanzi amaningi ferric chloride hexahydrate - oluluhlaza okuqinile. I namachibi Fe ³⁺ ion ukuthola umbala kusuka yellow ukuba ensundu. Ukuze isinqumo qualitative e isixazululo chloride ferric kukhona reagents:

• NaOH (ivela kwenze brown Fe (OH) _3);
• K ₄ [Fe (CN) _6] (kwenze livela KFe [Fe (CN) _6], loluhlata kwetjani);
• KCNS, NaCNS (thiocyanate ferric kwakhiwa Fe (CNS) ₃ obomvu).

Njengoba alulaze chloride ferric

yensimbi (III) chloride njengoba umbala onsundu ngokuphaphathekile noma abe bomvu yesixazululo ingatholakala inethiwekhi ukuhweba, uzilungiselele endaweni yokucwaninga noma ekhaya. Kulo mBhalo, ngempela zidinga ukushisa ukumelana non-metallic iziqukathi (ngengilazi, epulasitiki, Ceramic). Amanzi ukuncibilikisa usawoti kungenziwa othathwe empompini. Ukuphepha - abilisiwe noma distilled. Eliwu 50-70 ° C amanzi yafakwa esitsheni abese wathela izingxenyana ezincane izidakamizwa. Olinganise chloride namanzi ferric - 1: 3. Lapho ulungiselela isixazululo of crystalline ke amanzi iyadingeka ngaphansi, ngoba kuqukethwe hydrate crystalline (40% ngesisindo). Into yengezwe ikhambi kancane kancane, bakhonze ngamunye - mayelana 5-10 g Ngokushesha uthele lonke gibela is hhayi Kunconywa ngenxa yesimo okusheshayo ukusabela hydration. Awukwazi ukusebenzisa izinto zensimbi (nezinkezo, spatulas). Lo sawoti kufanele ziyoncibilika emanzini afudumele lapho zinhlayiya kufanele kube kahle exutshwe ketshezi ngokuphelele. It ngesivinini ukwengeza hydrochloric acid (1/10 ngesisindo sezinti zinhlayiya). Ngemva kokuma amahora ambalwa ezansi le kwenze kungenzeka ngenxa yokuba khona engxenyeni ukuhlolwa kanye kumiswa yensimbi hydroxide ngesikhathi yokusabela. It is elicwengekileyo isixazululo sitoko konsundu futhi agcinwe endaweni evaliwe isitsha plastic ezingeni lokushisa nokulinganisela ukungabi bikho kokukhanya kwelanga ngqo.

Ukusetshenziswa chloride ferric kanye Tinsita ezimbonini. ukusetshenziswa ekhaya

Iron nosawoti asetshenziswa emikhakheni eminingi. trivalent chloride metal isetshenziselwa ukwelapha amanzi, okusansimbi, futhi inki ukulungiswa. Ingqikithi elisetshenziswa zezimboni zamagama organic (kulethe, oxidant). Ikakhulukazi kwafunwa coagulating izakhiwo ion Fe ³⁺ e ukuhlanzwa effluents kamasipala nezezimboni. Ngaphansi isenzo chloride ferric izinhlayiya emihle zingaxazululeki coalesce futhi kwenze amanyela. Futhi ingxenye esibophezelayo contaminants encibilikayo ziyasuswa e zokukhuculula indle. I crystalline nosawoti anhydrous FeCl ₃ asetshenziswa izinqubo Etching izingcwecwe zensimbi ezilula. Into yengezwe ukhonkolo ukuze baqinise amandla ayo.

imihlola Chemical yesifunda amabhodi etching. izinyathelo zokuvikeleka

Popular chemical izidakamizwa ngoba Etching wesifunda amabhodi ephrintiwe - chloride ferric. Isixazululo le njongo ibhalwe kusuka 0,150 kg usawoti 0,200 ilitha lamanzi afudumele. Iqukethe athomu Fe ^3+, Cl ^-, futhi enkompolo ezakhiwe hydrolysis brown - hydroxide ferric. Ukuqhutshwa inqubo ngokuvumelana scheme: FeCl ₃ + 3HOH↔ Fe (OH) ₃ ⁺ 3Cl ^- + 3H +. Ububi kuyinto ukungcoliswa ibhodi ukuphendula byproducts okuyinto izinkinga etching olwengeziwe. Salt ngokwayo - ikhemikhali non-oluyingozi, kodwa inqubo nokuxhumana ngamanzi ukukhishwa evala ezonakalisayo. Umsebenzi kufanele kwenziwe endaweni evulekile noma endlini kahle umoya. Xhumana ne ikhambi isikhumba futhi nolwelwesi lwamafinyila okuholela ukucasulwa ubala futhi kungadala dermatitis. Kuyadingeka ukusebenzisa siqu izinto zokuzivikela (amagogolo, amagilavu). Ngo ukuxhumana isixazululo caustic kuyadingeka ukugeza isikhumba ngokuba namanzi amaningi.
