Qhov sib txawv tseem ceeb ntawm hlau II chloride thiab hlau III chloride yog tias Fe atom hauv hlau (II) chloride tshuaj lom neeg muaj lub xeev +2 oxidation thaum lub Fe atom hauv hlau (III) chloride compound muaj +3 oxidation xeev.
Iron(II) chloride thiab hlau (III) chloride yog ib qho tseem ceeb inorganic tebchaw ntawm cov tshuaj hlau (Fe). Iron II chloride kuj muaj npe hu ua ferrous chloride, thiab hlau III chloride yog hu ua ferric chloride.
Iron II Chloride yog dab tsi?
Iron(II) chloride yog FeCl2, qhov twg Fe atom nyob rau hauv +2 oxidation xeev. Nws tseem hu ua ferrous chloride. Cov compound no yog paramagnetic vim nws muaj unpaired electrons uas ua rau cov compound no tau attracted rau ib sab magnetic teb. Nws yog ib tug tan xim khoom nrog ib tug siab melting point. Muaj ob hom hlau (II) chloride ua daim ntawv anhydrous thiab daim ntawv tetrahydrate. Daim ntawv tetrahydrate tshwm nyob rau hauv cov xim daj ntseg. Txawm li cas los xij, muaj tsawg dua daim ntawv dihydrate ib yam nkaus.
Iron(II) chloride cov khoom tuaj yeem ua kom muaj zog los ntawm dej hauv daim ntawv ntawm ntsuab tetrahydrate. Cov tshuaj no yog cov dej-soluble heev, thiab nws muab cov tshuaj ntsuab daj ntseg thaum yaj hauv dej. Peb tuaj yeem tsim cov ntaub ntawv hydrated hlau (II) chloride los ntawm kev kho cov khib nyiab los ntawm steel ntau lawm nrog HCl acid. Hom kev daws teeb meem no tuaj yeem raug hu ua siv cov kua qaub lossis ua cawv txiv hmab. Tsis tas li ntawd, daim ntawv anhydrous ntawm cov tshuaj no tuaj yeem npaj tau los ntawm kev ntxiv cov hmoov hlau rau cov tshuaj HCl acid hauv methanol.
Daim duab 01: Hlau (II) Chloride Anhydrate
Muaj ntau daim ntawv thov ntawm hlau (II) chloride, suav nrog kev tsim cov hlau (III) chloride, rov tsim dua HCl acid los ntawm nws cov txheej txheem npaj, ua tus coagulation thiab flocculation tus neeg sawv cev hauv kev kho dej khib nyiab, muaj txiaj ntsig zoo rau kev tswj cov ntxhiab hauv Kev kho dej khib nyiab, thiab lwm yam.
Iron III Chloride yog dab tsi?
Iron(III) chloride yog FeCl3, qhov twg Fe atom nyob rau hauv +3 oxidation xeev. Nws tseem hu ua ferric chloride. Qhov no yog ib qho kev sib xyaw ua ke ntawm cov tshuaj hlau hlau. Nws yog crystalline khoom muaj xim sib txawv; cov xim nyob ntawm lub kaum sab xis saib, piv txwv li. cov muaju tshwm hauv cov xim ntsuab tsaus nrog lub teeb pom kev thaum cov muaju tshwm hauv ntshav liab nrog lub teeb xa mus.
Daim duab 02: Hlau III chloride nrog Transmitted Light
Muaj peb hom hydrated hlau (III) chloride compound. Lawv yog FeCl3.6H2O, FeCl3.2.5H2O, FeCl3.2H2O, thiab FeCl3.3.5H2O. Tus yam ntxwv, cov tshuaj aqueous ntawm ferric chloride yog xim daj.
Daim ntawv anhydrous ntawm hlau (III) chloride tuaj yeem npaj los ntawm kev sib xyaw ntawm cov ntsiab lus uas Fe tau cuam tshuam nrog Cl2 roj. Txawm li cas los xij, cov kev daws teeb meem ntawm ferric chloride tuaj yeem npaj tau los ntawm cov hlau, thiab cov txheej txheem suav nrog kev sib cais ntawm cov hlau ore hauv HCl acid, tom qab ntawd oxidation ntawm hlau (II) chloride nrog cov tshuaj chlorine lossis oxidation ntawm hlau (II) chloride nrog cov pa oxygen.
Qhov txawv ntawm Iron II Chloride thiab Iron III Chloride yog dab tsi?
Iron(II) chloride thiab Iron(III) chloride yog inorganic compounds uas muaj hlau (Fe) thiab chloride anions khi rau ib leeg los ntawm ionic bonding. Qhov sib txawv tseem ceeb ntawm hlau II chloride thiab hlau III chloride yog tias Fe atom hauv hlau (II) chloride chemical compound muaj +2 oxidation lub xeev thaum Fe atom hauv hlau (III) chloride compound muaj +3 oxidation xeev. Hlau (II) chloride muaj ob hom loj: daim ntawv dihydrated thiab daim ntawv tetrahydrate. Hlau (III) chloride muaj plaub hom loj: FeCl3.6H2O, FeCl3.2.5H2O, FeCl3.2H2O, thiab FeCl3.3.5H2O.
Hauv qab infographic qhia ntau qhov sib txawv ntawm hlau II chloride thiab hlau III chloride hauv daim ntawv tabular.
Summary – Iron II Chloride vs Iron III Chloride
Iron(II) chloride thiab Iron(III) chloride yog inorganic compounds uas muaj hlau (Fe) thiab chloride anions khi rau ib leeg los ntawm ionic bonding. Qhov sib txawv tseem ceeb ntawm hlau II chloride thiab hlau III chloride yog tias Fe atom hauv hlau (II) chloride chemical compound muaj +2 oxidation lub xeev whereas Fe atom hauv hlau (III) chloride compound muaj +3 oxidation xeev.
