Qhov sib txawv tseem ceeb ntawm leej faj, sulfate thiab sulfite yog cov Sulfur yog ib qho khoom thaum Sulfate thiab Sulfite yog Oxy-anions ntawm Sulfur.
Tshuaj muaj npe txawv heev. Sulfate (Sulphate), sulfite (Sulphite), thiab sulfur (Sulphur) yog peb cov tshuaj uas muaj ntau yam tshuaj thiab lub cev sib txawv. Ib tug kws tshuaj lossis ib tus neeg paub txog tshuaj yuav tsis muaj teeb meem rau qhov sib txawv ntawm 3 cov tshuaj no, tab sis rau ib tus neeg tsis paub, cov npe no zoo ib yam. Cia peb kawm paub qhov txawv ntawm leej faj, sulfate thiab sulfite.
Sulfur yog dab tsi?
Sulfur yog cov khoom tsis yog xim hlau. Cov cim tshuaj ntawm lub caij no yog S. Tsis tas li ntawd, tus lej atomic ntawm lub caij no yog 16. Tsis tas li ntawd, sulfur muaj nyob rau hauv ntau lub tebchaw thiab ntau hom. Yog li ntawd, peb hu nws ib tug allotropic keeb. Nyob rau hauv daim ntawv ntshiab, leej faj tuaj yeem muaj ntau daim ntawv lub cev. Feem ntau yog cov crystalline daj xim khoom uas yog nkig heev.
Daim duab 01: Sulfur Compound
Tsis tas li ntawd, leej faj yog qhov muaj zog heev thiab muaj ntau yam kev siv. Nws muaj txiaj ntsig zoo hauv kev tsim cov hmoov phom, tshuaj tua kab thiab tshuaj noj thiab lwm yam.
YSulphate yog dab tsi?
Sulfate yog ib qho oxy-anion ntawm Sulfur (Ib qho oxy-anion yog oxygen uas muaj cov ion tsis zoo). Txawm hais tias koj tsis paub txog cov ion no, koj yuav tsum paub txog sulfuric acid. Sulfuric acid muaj ob H+ ions thiab ib qho sulfate ion. Cov mis empirical ntawm no ion yog SO42-. Nws yog polyatomic anion. Yog li ntawd, nyob rau hauv no ion, Sulfur atom yog lub hauv paus atom thiab plaub oxygen atoms yog covalently khi rau lub hauv paus atom.
Daim duab 02: Sulfate Anion
Tsis tas li ntawd, ob lub pa oxygen atom khi ntawm ob daim ntawv cog lus thiab ob qho tib si ib leeg. Yog li ntawd, ib qho kev khi oxygen atoms Ameslikas muaj Hydrogen atom hauv txhua tus ntawm lawv. Thaum cov ntawv ion no, nws tso H+ thiab nqa cov nqi tsis zoo. Raws li, lub geometry ntawm ion yog tetrahedral qhov twg oxygen atoms nyob rau hauv plaub fab ntawm lub tetrahedron.
Sulphite yog dab tsi?
Sulfite yog lwm oxy-anion ntawm sulfur. Cov mis empirical ntawm no ion yog SO32- Nws kuj muaj ob yam tsis zoo xws li sulfate ion. Yog li ntawd, qhov sib txawv ntawm sulfate thiab sulfite nyob rau hauv tus naj npawb ntawm atoms tam sim no nyob rau hauv lub ion. Ntawm no, cov ion no muaj peb cov pa oxygen atoms ob npaug rau lub hauv paus Sulfur atom. Thaum H+ions tshwm sim, cov sulfite ua sulfurous acid.
Tsis tas li ntawd, lub geometry ntawm no anion yog trigonal pyramidal. Yog li, Oxygen atoms nyob ntawm peb ntug, thiab ib khub ntawm electrons nyob rau saum toj.
Daim duab 03: Sulfite Anion
Saib nws cov khoom, sulfurous acid kuj tsis muaj zog dua li sulfuric acid.
Qhov txawv ntawm Sulfur, Sulfate thiab Sulfite yog dab tsi?
Sulfur yog cov khoom tsis yog xim hlau uas muaj tus lej atomic 16. Whereas, sulfate yog ib qho oxy-anion ntawm sulfur uas muaj cov tshuaj formula SO4 2 - Ntawm qhov tod tes, sulfite kuj yog oxy-anion ntawm sulfur uas muaj cov tshuaj formula SO32- Yog li ntawd, Qhov sib txawv tseem ceeb ntawm leej faj, sulfate thiab sulfite yog cov leej faj yog ib qho khoom thaum cov sulfate thiab sulfite yog oxy-anions ntawm Sulfur. Raws li, lwm qhov sib txawv ntawm leej faj, sulfate thiab sulfite yog qhov loj ntawm leej faj yog 32.065 amu thaum lub loj ntawm sulfate yog 96.06 g / mol. Ntawm qhov tod tes, qhov loj ntawm sulfite yog 80.06 g / mol.
Cov lus qhia hauv qab no ntawm qhov sib txawv ntawm leej faj, sulfate thiab sulfite qhia ntau qhov sib txawv uas muaj nyob ntawm peb cov tshuaj no.
Summary – Sulfur, Sulfate vs Sulfite
Sulfur yog cov khoom tsis yog xim hlau uas koom nrog hauv kev tsim cov khoom sib txawv. Ntawm qhov tsis sib xws, sulfate thiab sulfite yog oxy-anions tsim los ntawm kev sib xyaw ntawm sulfur thiab oxygen. Yog li ntawd, qhov sib txawv tseem ceeb ntawm leej faj, sulfate, thiab sulfite yog cov leej faj yog ib yam khoom uas cov sulfate thiab sulfite yog oxy-anions ntawm leej faj.
