Ob qho tshuaj chlorine thiab chlorine dioxide yog cov khoom siv roj. Lawv muaj cov tshuaj sib txawv thiab lub cev sib txawv thiab yog li, kev siv sib txawv. Txij li cov tshuaj chlorine yog ib pawg 7 tshuaj lom neeg, feem ntau oxidation xeev ntawm nws yog -1. Txawm li cas los xij, chlorine atom hauv chlorine dioxide muaj +4 oxidation xeev.
Chlorine yog dab tsi?
Chlorine yog ib qho gaseous compound uas muaj cov tshuaj Cl2 Nws yog cov pa daj daj-ntsuab ntawm chav tsev kub thiab siab. Nws ua raws li tus neeg sawv cev tsis tshua muaj zog, yog li, yog tus neeg sawv cev oxidizing muaj zog. Ntxiv mus, nws muaj ib tug pungent, irritating tsw. Cov ntxhiab no zoo ib yam li tshuaj dawb. Lub npe IUPAC ntawm cov roj no yog "molecular chlorine".
Daim duab 01: chlorine Gas Xim
Cov molar loj ntawm cov roj chlorine yog 70.9 g / mol. Ob lub chlorine atoms nyob rau hauv no molecule yog covalently bonded rau ib leeg. Peb hu nws "diatomic gas" vim hais tias muaj ob lub atoms txuas rau ib leeg rau ib lub molecule. Kev nqus pa ntawm cov pa no yog tshuaj lom thiab nws kuj yog ib qho irritant rau lub qhov muag. Cov roj yog me ntsis soluble hauv dej thiab tuaj yeem ua rau liquefy ntawm -35 ◦C. Txawm li cas los xij, peb tuaj yeem yooj yim liquefy cov roj no los ntawm kev siv lub siab tsim nyog ntawm chav tsev kub. Ntxiv mus, cov roj no tsis yog hluav taws kub, tab sis nws tuaj yeem txhawb kev sib txuas.
Tseem ceeb tshaj, cov pa roj no yog tshuaj lom yog tias peb nqus nws. Cov roj chlorine hnyav dua li huab cua. Yog li nws nyiam sau nyob rau thaj chaw qis ntawm huab cua. Cov ntsiab lus melting thiab boiling yog -101 ° C thiab -35 ° C feem. Nws muaj txiaj ntsig zoo li tshuaj tua kab mob hauv ntau qhov kev lag luam, kev kho dej, ua tsov rog gases, thiab lwm yam.
Chlorine Dioxide yog dab tsi?
Chlorine dioxide yog ib qho inorganic compound uas muaj cov tshuaj formula ClO2 Nws yog xim daj rau xim liab. Cov roj no crystallizes ntawm -59 ° C uas zoo li cov xim txiv kab ntxwv-xim muaju. Qhov no yog ib qho oxide ntawm chlorine. Qhov hnyav ntawm molar yog 67.45 g / mol. Nws muaj cov ntxhiab tsw qab. Cov ntsiab lus melting thiab boiling yog -59 ° C thiab 11 ° C feem. Qhov no yog qhov nruab nrab nruab nrab thiab txawv ntawm cov tshuaj chlorine. Nws muaj dej solubility siab heev. Tshwj xeeb tshaj yog nws tuaj yeem yaj hauv dej txias. Lub solubility yog li 10 npaug siab dua li cov roj chlorine. Ntxiv mus, nws tsis hydrolyze thaum peb yaj nws hauv dej. Yog li ntawd, nws tseem zoo li cov roj yaj hauv dej. Lub xeev oxidation ntawm chlorine atom nyob rau hauv no molecule yog +4. Txij li thaum lub molecule no muaj ib qho khib ntawm electrons, nws yog paramagnetic.
Daim duab 02: Liquefied Chlorine Dioxide
Cov kev siv loj ntawm cov roj no suav nrog hauv cov tshuaj dawb huv ntoo, hauv cov tshuaj chlorine tsis muaj tshuaj dawb, kev kho dej haus, ua kev kho fumigant, thiab lwm yam.
Qhov txawv ntawm chlorine thiab chlorine dioxide yog dab tsi?
Chlorine yog ib qho gaseous compound uas muaj cov tshuaj formula Cl2Ntawm qhov tod tes, chlorine dioxide yog ib qho inorganic compound uas muaj cov tshuaj formula ClO 2 Lub melting thiab boiling cov ntsiab lus ntawm chlorine gas yog tsawg heev piv rau chlorine dioxide. Tseem ceeb tshaj, chlorine dioxide yog dej soluble heev; nws dissolves txawm nyob rau hauv dej txias. Qhov solubility no yog li 10 npaug siab dua li cov roj chlorine. Ob lub tebchaw no muab los ntawm cov tshuaj chlorine. Qhov sib txawv tseem ceeb ntawm cov tshuaj chlorine thiab chlorine dioxide yog tias lub xeev oxidation ntawm cov tshuaj chlorine atom hauv cov roj chlorine yog xoom whereas lub xeev oxidation ntawm chlorine atom hauv chlorine dioxide yog +4.
Cov duab hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm cov tshuaj chlorine thiab chlorine dioxide hauv daim ntawv teev npe.
Summary – Chlorine vs Chlorine Dioxide
Chlorine thiab chlorine dioxide yog cov khoom sib xyaw ua ke ntawm chav tsev kub thiab siab. Qhov sib txawv ntawm cov tshuaj chlorine thiab chlorine dioxide yog tias lub xeev oxidation ntawm chlorine atom hauv cov roj chlorine yog xoom whereas lub xeev oxidation ntawm chlorine atom hauv chlorine dioxide yog +4.
