Qhov sib txawv tseem ceeb ntawm sulfonate thiab sulfate yog sulfonate yog anion uas tsim los ntawm sulfonic acid, whereas sulfate yog anion uas tsim los ntawm sulfuric acid.
Txawm hais tias cov ntsiab lus sulfonate thiab sulfate suab zoo ib yam, lawv yog cov anions sib txawv kiag li. Yog tias peb saib lawv cov qauv tshuaj, sulfonate muaj pawg R, uas yog pawg organic, thaum sulfate tsis muaj R pawg.
Sulfonate yog dab tsi?
Sulfonate yog ib qho anion uas muaj cov tshuaj formula R-SO3− Ntawm no, pawg R yog pawg organic. Thiab, qhov no anion originates los ntawm sulfonic acid. Feem ntau, cov anions ruaj khov nyob rau hauv dej thiab tsis muaj xim nyob rau hauv aqueous tov. Ntxiv mus, cov anions no tsis-oxidizing. Cov qauv tshuaj muaj raws li hauv qab no:
Sulfonic acids yog cov acids muaj zog. Txij li thaum sulfonate yog lub hauv paus conjugate ntawm sulfonic acid, sulfonate yog lub hauv paus tsis muaj zog. Lub xeev oxidation ntawm sulfur atom nyob rau hauv no anion yog +5, thiab tag nrho cov nqi yog -1. Zoo ib yam li sulfate anion, anion no kuj muaj ob daim ntawv cog lus S=O tab sis muaj R-S daim ntawv cog lus thiab S-O daim ntawv cog lus raws li ib daim ntawv cog lus (sulfate anion muaj ob daim ntawv cog lus ib leeg).
YSulphate yog dab tsi?
Sulfate yog ib qho anion uas muaj cov tshuaj formula SO4−2 Nws pib los ntawm sulfuric acid. Thiab, qhov no anion muaj plaub oxygen atoms txuas nrog lub hauv paus sulfur atom, thiab cov anion muaj tetrahedral geometry. Cov sulfur atom muaj oxidation lub xeev +6. Muaj ob lub pa oxygen atom nrog -1 nqi.
Daim duab 02: Cov qauv ntawm Sulfate Anion
Peb tuaj yeem tsim cov anion no siv ob txoj hauv kev loj:
- Kho cov hlau lossis hlau oxide nrog sulfuric acid
- Oxidation hlau sulfides rau hauv sulfites
Nrog qee qhov tshwj xeeb xws li calcium sulfate thiab strontium sulfate, tag nrho lwm cov sulfate compounds paub tias yog dej-soluble. Tsis tas li ntawd, cov anion no tuaj yeem ua cov ligand hauv kev sib koom ua ke los ntawm kev sib txuas nrog ib qho oxygen atom (monodentate ligand) lossis ob (bidentate ligand).
Qhov txawv ntawm Sulfonate thiab Sulfate yog dab tsi?
Sulfonate yog ib qho anion uas muaj cov tshuaj formula R-SO3- thaum Sulfate yog anion muaj cov tshuaj SO 4−2Qhov sib txawv tseem ceeb ntawm sulfonate thiab sulfate yog sulfonate yog ib qho anion uas tsim los ntawm sulfonic acid, whereas sulfate yog anion uas tsim los ntawm sulfuric acid.
Ntxiv mus, lub xeev oxidation ntawm sulfur atom hauv sulfonate yog +5, thiab hauv sulfate, nws yog +6. Tsis tas li ntawd, tag nrho cov nqi ntawm sulfonate anion yog -1, thiab hauv sulfate anion, nws yog -2. Yog li, qhov no kuj yog qhov sib txawv ntawm sulfonate thiab sulfate.
Summary – Sulfonate vs Sulfate
Sulfonate yog ib qho anion uas muaj cov tshuaj formula R-SO3- thaum Sulfate yog anion muaj cov tshuaj SO 4−2. Qhov sib txawv tseem ceeb ntawm sulfonate thiab sulfate yog sulfonate yog ib qho anion uas tsim los ntawm sulfonic acid, whereas sulfate yog anion uas tsim los ntawm sulfuric acid.
