Qhov sib txawv tseem ceeb ntawm carbon tetrachloride thiab sodium chloride yog tias carbon tetrachloride yog covalent tshuaj compound whereas sodium chloride yog ib qho tshuaj ionic compound.
Ob qho tib si carbon tetrachloride thiab sodium chloride yog cov tshuaj chlorine uas muaj tshuaj lom neeg. Txawm li cas los xij, ob qho tshuaj sib xyaw ua ke sib txawv ntawm ib leeg raws li cov qauv tshuaj, cov khoom thiab kev siv.
Carbon Tetrachloride yog dab tsi?
Carbon tetrachloride yog cov tshuaj sib xyaw uas muaj cov tshuaj formula CCl4. Nws feem ntau hu ua "tetrachloromethane". Carbon tetrachloride yog cov kua tsis muaj xim uas muaj ntxhiab tsw qab. Yog li ntawd, nws yog ib qho yooj yim mus ntes cov compound no los ntawm nws cov ntxhiab txawm nyob rau theem qis.
Daim duab 01: Cov qauv ntawm Carbon Tetrachloride
Cov molar loj ntawm carbon tetrachloride yog 153.81 g / mol. Nws muaj qhov melting point ntawm -22.92 ° C, thiab qhov kub ntawm 76.72 ° C. Thaum xav txog geometry ntawm carbon tetrachloride molecule, nws muaj tetrahedral geometry. Muaj plaub chlorine atoms sib txuas rau ib qho carbon atom, thiab cov ces kaum ntawm cov molecules sib npaug. Yog li ntawd, peb hu nws "symmetrical geometry". Qhov no geometry ua rau cov compound nonpolar. Nws zoo ib yam li cov qauv ntawm methane molecule, uas muaj plaub lub atoms hydrogen sib txuas rau ib qho atom carbon.
Muaj ntau yam kev siv carbon tetrachloride. Ua ntej qhov txwv tsis pub, qhov sib xyaw no tau siv los tsim CFC hauv cov nplai loj. Niaj hnub no, peb tsis tsim CFC vim nws ua rau lub ozone txheej. Cov pa roj carbon tetrachloride yog cov khoom tseem ceeb hauv lava teeb. Ib zaug nws yog cov kuab tshuaj nrov, tab sis tam sim no peb tsis siv nws vim nws cov teebmeem kev noj qab haus huv. Ntxiv mus, peb tau siv dav hauv cov tshuaj tua hluav taws, ua cov khoom ua ntej rau cov tub yees thiab ua cov tshuaj ntxuav.
Sodium Chloride yog dab tsi?
Sodium chloride yog ib qho inorganic compound uas muaj cov tshuaj formula NaCl. Cov molar loj ntawm cov tshuaj no yog 58.44 g / mol. Nyob rau hauv chav tsev kub thiab siab, sodium chloride tshwm nyob rau hauv solid-state, raws li tsis muaj kob muaju. Tsis tas li ntawd, cov khoom no tsis muaj ntxhiab tsw. Hauv nws daim ntawv ntshiab, sodium chloride tsis tuaj yeem nqus dej vapor, uas txhais tau tias, nws tsis yog hygroscopic.
Daim duab 02: Cov Crystals ntawm Sodium Chloride
Sodium chloride yog ntsev ntawm sodium, yog li nws yog ib qho ionic compound. Cov tshuaj no muaj ib qho chorine atom rau txhua tus sodium atom ntawm cov molecule. Sodium chloride ntsev yog lub luag haujlwm rau salinity ntawm seawater. Lub melting point yog 801◦C thaum lub boiling point yog 1413◦C. Nyob rau hauv sodium chloride crystals, txhua sodium cation yog ib puag ncig nrog rau chloride ions thiab vice versa. Yog li ntawd, peb hu rau lub tshuab siv lead ua ua lub ntsej muag-centred cubic system.
Sodium chloride dissolves nyob rau hauv siab polar compounds xws li dej. Ntawm no, dej molecules nyob ib puag ncig txhua cation thiab anion. Txhua ion feem ntau muaj rau dej molecules nyob ib ncig ntawm lawv. Txawm li cas los xij, pH ntawm aqueous sodium chloride nyob ib ncig ntawm pH7 vim qhov tsis muaj zog ntawm cov tshuaj chloride ion. Peb hais tias tsis muaj kev cuam tshuam ntawm sodium chloride ntawm pH ntawm cov tshuaj.
Qhov txawv ntawm Carbon Tetrachloride thiab Sodium Chloride yog dab tsi?
Ob qho tib si carbon tetrachloride thiab sodium chloride yog cov tshuaj chlorine uas muaj tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm carbon tetrachloride thiab sodium chloride yog tias carbon tetrachloride yog covalent chemical compound whereas sodium chloride yog ib qho tshuaj ionic. Ntxiv mus, carbon tetrachloride dissolves nyob rau hauv nonpolar solvents thaum sodium chloride dissolves nyob rau hauv polar solvents.
Hauv qab infograhic qhia txog qhov sib txawv ntawm carbon tetrachloride thiab sodium chloride hauv daim ntawv tabular.
Summary – Carbon Tetrachloride vs Sodium Chloride
Carbon tetrachloride thiab sodium chloride yog sib txawv ntawm ib leeg raws li cov qauv tshuaj, cov khoom thiab lawv daim ntawv thov. Qhov sib txawv tseem ceeb ntawm carbon tetrachloride thiab sodium chloride yog tias carbon tetrachloride yog covalent chemical compound whereas sodium chloride yog ib qho tshuaj ionic compound.
