Qhov sib txawv tseem ceeb ntawm bromine thiab mercury yog tias bromine tsuas yog halogen nkaus xwb uas nyob hauv lub xeev ua kua ntawm chav tsev kub, qhov mercury tsuas yog cov hlau uas nyob hauv cov kua hauv chav sov.
Ob leeg bromine thiab mercury tuaj yeem pom hauv lawv lub xeev ua kua ntawm tus qauv ntsuas kub thiab siab. Txawm li cas los xij, bromine yog nonmetal thaum mercury yog hlau.
Bromine yog dab tsi?
Bromine yog cov khoom siv tshuaj muaj cov cim Br thiab atomic tooj 35. Cov tshuaj no yog nyob rau hauv pawg halogens (pawg 7) nyob rau hauv lub sij hawm ntawm lub ntsiab lus. Peb tuaj yeem pom nws hauv nws lub xeev ua kua ntawm chav tsev kub thiab siab; Nws tsuas yog halogen nkaus xwb uas tshwm sim hauv cov kua hauv lub xeev ntawm tus mob no vim tias fluorine thiab chlorine tshwm sim raws li cov pa roj thaum iodine tshwm sim hauv lub xeev (fluorine, chlorine thiab iodine yog lwm cov tswv cuab tseem ceeb ntawm pawg halogen). Bromine tuaj yeem pom raws li cov kua liab-xim av fuming uas nkag tau yooj yim evaporates los tsim cov roj sib xws. Ntxiv mus, peb tuaj yeem hais tias cov khoom ntawm bromine yog nruab nrab ntawm cov tshuaj chlorine thiab iodine tshuaj.
Daim duab 01: Bromine
Bromine, nyob rau hauv nws daim ntawv tseem ceeb, yog heev reactive; yog li ntawd, peb tsis tuaj yeem soj ntsuam lub caij no raws li lub hauv paus dawb hauv cov xwm txheej. Txawm li cas los xij, peb tuaj yeem pom nws ua cov xim tsis muaj xim tsis muaj xim crystalline ntxhia halide ntsev daim ntawv uas zoo sib xws rau cov lus ntsev. Hauv kev lag luam nplai, peb tuaj yeem yooj yim rho tawm bromine los ntawm brine pas dej.
Zoo ib yam li tag nrho lwm cov ntsiab lus halogens, bromine muaj qhov muaj txiaj ntsig ntawm 1; Yog li, nws tuaj yeem ua tus neeg sawv cev oxidizing muaj zog uas tuaj yeem hnov mob nrog ntau lub ntsiab lus txhawm rau ua kom tiav nws lub plhaub sab nrauv. Thaum piv rau nws cov neeg zej zog halogens, bromine tsis tshua muaj zog dua li cov tshuaj chlorine tab sis ntau reactive dua iodine. Bromine feem ntau tshwm sim li Br2 molecules, qhov twg muaj Van der Waals rog ntawm bromine molecules.
Mercury yog dab tsi?
Mercury yog cov khoom siv tshuaj muaj lub cim Hg thiab atomic naj npawb 80. Nws yog cov khoom siv hlau thiab tsuas yog cov khoom siv hlau uas tshwm sim hauv nws cov kua hauv lub xeev ntawm chav tsev kub thiab siab. Nws zoo nkaus li ci, silvery kua. Peb tuaj yeem pom mercury hauv cov pob zeb hauv av hauv daim ntawv ntawm mercuric sulfide. Cov hlau no yog ib yam khoom uas tsis tshua muaj nyob hauv lub ntiaj teb daim tawv nqaij.
Daim duab 02: Mercury
Mercury tuaj yeem pom zoo li cov hlau ua kua hnyav uas muaj hluav taws xob tsis zoo piv rau lwm cov hlau. Txawm li cas los xij, cov khoom mercury yog malleable thiab ductile thiab tuaj yeem txiav nrog rab riam. Cov tshuaj no tsis cuam tshuam nrog feem ntau cov kua qaub xws li dilute sulfuric acid, tab sis qee cov oxidizing acids xws li concentrated sulfuric acid thiab nitric acid, aqua regia tuaj yeem yaj cov hlau no kom muab sulfate, nitrate thiab chloride cov ntaub ntawv mercury. Ntxiv mus, mercury tuaj yeem yaj ntau cov hlau xws li kub thiab nyiaj, tsim cov amalgams.
Qhov txawv ntawm Bromine thiab Mercury yog dab tsi?
Bromine yog nonmetal thaum mercury yog hlau. Qhov sib txawv tseem ceeb ntawm bromine thiab mercury yog tias bromine tsuas yog halogen nkaus xwb nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub, hos mercury yog tib yam hlau uas nyob hauv cov kua hauv lub xeev ntawm chav tsev kub. Ntxiv mus, bromine tshwm sim li Br2 hauv cov pob zeb hauv av thaum mercury tshwm sim raws li cov hlau ib txwm muaj, los yog cov ntaub ntawv ntxhia.
Cov lus hauv qab no teev ntau qhov sib txawv ntawm bromine thiab mercury.
Summary – Bromine vs Mercury
Ob leeg bromine thiab mercury tuaj yeem pom hauv cov kua hauv lub xeev ntawm chav tsev kub thiab siab. Bromine yog nonmetal thaum mercury yog hlau. Qhov sib txawv tseem ceeb ntawm bromine thiab mercury yog tias bromine tsuas yog halogen nkaus xwb nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub, whereas mercury yog tib yam hlau uas nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub.
