Chlorine yog dab tsi?
Chlorine yog cov roj ntawm chav tsev kub uas muaj cov tshuaj formula Cl2Nws muaj cov xim daj daj daj, thiab nws yog ib tus neeg ua haujlwm tsis tshua muaj zog. Yog li ntawd, nws tuaj yeem ua tus neeg sawv cev oxidizing muaj zog. Tsis tas li ntawd, cov roj no muaj pungent thiab irritating tsw zoo li cov tshuaj dawb uas peb ib txwm siv. Nyob rau hauv IUPAC nomenclature, peb lub npe no compound li molecular chlorine.
Cov molar loj ntawm cov tshuaj no yog 70.9 g / mol. Cov tshuaj chlorine gas molecule muaj ob lub chlorine atoms sib koom ua ke ntawm covalent chemical bond. Yog li ntawd peb muab nws lub npe hu ua diatomic molecule. Ntxiv mus, cov roj no yog me ntsis soluble hauv dej. Peb tuaj yeem ua kom cov roj no liquefied ntawm -35◦C. Los yog lwm yam peb tuaj yeem ua rau nws los ntawm kev siv lub siab sab nraud los ua kom cov pa ntawm chav tsev kub. Cov roj chlorine yog qhov kub hnyiab, tab sis nws tuaj yeem pab ua kom tawg.
Daim duab 01: Liquefied Chlorine Gas
Kev nqus cov pa chlorine yog tshuaj lom. Nws kuj ua raws li irritant rau qhov muag. Ntxiv rau qhov ntawd, cov pa roj no hnyav dua li cov huab cua ib txwm muaj. Yog li ntawd, nws yooj yim sau nyob rau hauv qis cua. Txij li thaum nws tshwm sim raws li ib tug roj ntawm chav tsev kub, lub melting thiab boiling ntsiab lus yog -101 ° C thiab -35 ° C feem. Thaum xav txog kev siv cov roj no, muaj peb qhov kev siv loj; Kev siv tshuaj tua kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob. Tsis tas li ntawd xwb, muaj qee tus neeg siv nws los ua riam phom tshuaj lom neeg thiab.
Sodium Hypochlorite yog dab tsi?
Sodium hypochlorite yog ib qho inorganic compound uas muaj cov tshuaj formula NaOCl. Nws yog xim ntsuab-daj khoom ntawm chav tsev kub. Cov molecule muaj sodium cation thiab hypochlorite anion. Ob lub ions txuas nrog ib leeg los ntawm kev sib cuam tshuam electrostatic. Ntxiv mus, peb tuaj yeem faib cov ntsiab lus no raws li sodium ntsev ntawm hypochlorous acid, xav txog cov niam txiv molecule ntawm cov compound; niam txiv molecule yog hypochlorous acid.
Daim duab 02: Sodium Hypochlorite Molecule
Cov molar loj yog 74.44 g / mol. Nws muaj cov ntxhiab tsw zoo li chlorine. Txawm li cas los nws muaj ib tug qab zib tsw. Txij li thaum nws muaj nyob rau hauv cov khoom ntawm chav tsev kub, cov ntsiab lus melting thiab boiling yog qhov zoo; melting thiab boiling ntsiab lus yog 18 ° C thiab 101 ° C raws.
Ntau peb lub npe tshuaj ntsuab-daj raws li sodium hypochlorite vim tias cov tshuaj no ua los ntawm kev sib cais ntawm cov khoom hauv dej muab cov kua tshuaj dawb uas peb siv hauv tsev. Tsis tas li ntawd, cov khoom sib txuas tsis ruaj khov. Yog li nws tuaj yeem decompose explosively. Peb tuaj yeem crystallize no compound raws li nws cov pentahydrate. Cov hydrated compound no ruaj khov heev; Yog li, peb tuaj yeem khaws cia rau hauv lub tub yees. Nyob rau hauv nws cov kua bleach daim ntawv, cov tshuaj compound nyob rau hauv cov tshuaj liberate chlorine gas. Txawm li cas los xij, cov tshuaj no tsis yog tshuaj lom lossis corrosive zoo li cov roj chlorine. Kev siv loj ntawm cov tshuaj no suav nrog tshuaj dawb, ntxuav, tshuaj tua kab mob, deodorizing, kho dej khib nyiab, thiab lwm yam.
Qhov txawv ntawm chlorine thiab Sodium Hypochlorite yog dab tsi?
Chlorine yog ib qho roj ntawm chav tsev kub uas muaj cov tshuaj formula Cl2 whereas sodium hypochlorite yog ib qho inorganic compound uas muaj cov tshuaj formula NaOCl. Qhov no yog qhov sib txawv ntawm cov tshuaj chlorine thiab sodium hypochlorite. Ob qho no yog ib qho tseem ceeb xws li tshuaj dawb huv, tshuaj tua kab mob, thiab lwm yam. Thaum xav txog cov tshuaj sib txuas, qhov sib txawv ntawm cov tshuaj chlorine thiab sodium hypochlorite yog tias cov tshuaj chlorine muaj covalent tshuaj bond ntawm ob lub chlorine atoms thaum lub sodium hypochlorite muaj electrostatic attraction quab yuam ntawm sodium cation. thiab hypochlorite anion. Peb tuaj yeem xav txog lawv qhov tshwm sim raws li qhov sib txawv tseem ceeb ntawm chlorine thiab sodium hypochlorite. Chlorine yog xim daj daj daj ntseg thaum sodium hypochlorite yog xim ntsuab-daj khoom ntawm chav tsev kub. Ntxiv mus, cov roj chlorine muaj tshuaj lom heev thaum piv rau cov tshuaj lom ntawm sodium hypochlorite.
Cov lus qhia hauv qab no muab cov ntaub ntawv ntxiv txog qhov sib txawv ntawm cov tshuaj chlorine thiab sodium hypochlorite.
Summary – Chlorine vs Sodium Hypochlorite
Ob lub chlorine gas thiab sodium hypochlorite yog ib qho tseem ceeb ua cov tshuaj bleaching thiab tshuaj tua kab mob. Chlorine gas nws tus kheej yog oxidative thaum sodium hypochlorite tuaj yeem tso cov roj chlorine rau nws cov ntawv thov. Qhov sib txawv tseem ceeb ntawm cov tshuaj chlorine thiab sodium hypochlorite yog cov tshuaj chlorine yog xim daj daj daj thaum sodium hypochlorite yog cov khoom ntsuab-daj ntawm chav tsev kub.
