Qhov sib txawv tseem ceeb ntawm sulfite thiab sulfur trioxide yog sulfite yog ib qho ionic compound uas muaj cov sulfate (IV) anion whereas sulfur trioxide yog cov tsis-ionic compound.
Sulfite thiab sulfur trioxide yog cov tshuaj sib xyaw uas muaj cov sulfur atoms. Lub sij hawm sulfites xa mus rau ionic compounds uas muaj sulfite anion khi rau txawv cations. Sulfur trioxide yog ib qho inorganic compound uas muaj cov tshuaj formula SO3.
Sulphite yog dab tsi?
Lub sij hawm sulfites xa mus rau ionic compounds uas muaj sulfite anion khi rau txawv cations. Cov tshuaj formula rau sulfite anion yog SO32-Nws tseem muaj npe hu ua sulfate (IV) ion qhov twg sulfur atom hauv anion muaj +4 oxidation xeev. Lub sulfite anion yog conjugate puag ntawm bisulfite. Sulfite compounds feem ntau tshwm sim hauv qee cov khoom noj thiab hauv tib neeg lub cev. Tsis tas li ntawd, sulfites muaj txiaj ntsig zoo li cov khoom noj ntxiv thiab tuaj yeem tsim cov pob thaum lawv tshwm sim ua ke nrog sulfur dioxide hauv cov zaub mov.
Daim duab 01: Cov qauv ntawm Sulfite Anion
Muaj peb lub peev xwm resonance rau sulfite anion. Nyob rau hauv txhua tus qauv resonance, peb tuaj yeem pom tias cov sulfur atom yog ob npaug rau ib qho ntawm peb cov pa oxygen atoms. Yog li ntawd, txhua tus qauv resonance muaj leej faj rau oxygen ob daim ntawv cog lus nrog rau tus nqi ntawm xoom, thaum cov sulfur atom yog sib koom nrog ob lub pa oxygen atom los ntawm ib daim ntawv cog lus. Lwm ob lub pa oxygen atom no nqa tus nqi ntawm -1 ntawm txhua lub atom oxygen. Cov nqi raug cai no pab txhawb rau tag nrho cov nqi (-2) ntawm sulfite anion. Muaj ib leeg electron khub ntawm leej faj atom. Yog li ntawd, lub geometry ntawm no anion yog trigonal pyramidal.
Sulfur Trioxide yog dab tsi?
Sulfur trioxide yog ib qho inorganic compound uas muaj cov tshuaj formula SO3. Nws suav hais tias yog qhov tseem ceeb tshaj plaws kev lag luam oxide compound ntawm sulfur. Cov khoom no tuaj yeem muaj nyob hauv ntau hom: hauv lub xeev roj, crystalline trimer state, thiab cov khoom polymer. Txawm li cas los xij, nws yog cov khoom lag luam feem ntau yog xim tsis muaj xim rau dawb crystalline khoom uas tuaj yeem fume hauv huab cua. Cov ntxhiab ntawm qhov sib xyaw no tuaj yeem sib txawv, tab sis nws tsim pungent vapour.
Peb tuaj yeem soj ntsuam peb cov qauv resonance ntawm sulfur trioxide compound. Yog li ntawd, qhov tseeb molecule yog ib tug hybrid qauv ntawm peb resonance qauv. Cov qauv hybrid muaj trigonal planar geometry. Ntawm no, sulfur atom nyob rau hauv nruab nrab ntawm lub molecule, thiab nws muaj +6 oxidation xeev. Tus nqi raug cai ntawm cov sulfur atom yog xoom. Cov qauv resonance qhia tau hais tias peb cov sulfur rau oxygen covalent bonds sib npaug hauv daim ntawv cog lus ntev.
Daim duab 02: Resonance ntawm Sulfur Trioxide Molecule
Cov khoom no yog ib qho tseem ceeb raws li ib tug reagent nyob rau hauv sulfonation tshuaj. Cov tshuaj tiv thaiv no yog qhov tseem ceeb hauv kev tsim cov tshuaj ntxuav tes, tshuaj zawv plaub hau, thiab tshuaj sib xyaw.
Qhov txawv ntawm Sulfite thiab Sulfur Trioxide yog dab tsi?
Lub sij hawm sulfites hais txog cov ionic compounds uas muaj sulfite anion khi rau ntau cations. Sulfur trioxide yog ib qho inorganic compound uas muaj cov tshuaj formula SO3. Qhov sib txawv tseem ceeb ntawm sulfite thiab sulfur trioxide yog sulfite yog ib qho ionic compound uas muaj sulfate (IV) anion, hos sulfur trioxide yog cov tsis-ionic compound.
Cov hauv qab no infographic teev qhov sib txawv ntawm sulfite thiab sulfur trioxide hauv daim ntawv tabular rau ib sab sib piv.
Summary – Sulfite vs Sulfur Trioxide
Lub sij hawm sulfite yog hais txog cov ionic compounds uas muaj sulfite anion khi rau sib txawv cations. Sulfur trioxide yog ib qho inorganic compound uas muaj cov tshuaj formula SO3. Qhov sib txawv tseem ceeb ntawm sulfite thiab sulfur trioxide yog sulfites yog cov ionic compounds uas muaj cov sulfate (IV) anion, hos sulfur trioxide yog cov tsis-ionic compound.
