Qhov sib txawv tseem ceeb ntawm isopoly thiab heteropoly acids yog tias isopoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub los yog anions, whereas heteropoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub sib txawv los yog anions.
Y A poly acid yog ib qho acidic compound uas tsim los ntawm kev sib xyaw ntawm ob cov kua qaub los ntawm kev tshem tawm cov dej molecule. Yog tias cov kua qaub sib xyaw ua ke zoo sib xws, ces cov kua qaub uas tshwm sim yog ib qho isopoly acid. Tab sis yog tias cov khoom kawg yog kev sib xyaw ntawm ob lossis ntau hom acids, ces peb hu nws ua heteropoly acid.
Isopoly Acids yog dab tsi?
Isopoly acids yog inorganic acidic compounds uas tsim los ntawm kev sib xyaw ntawm cov kua qaub los yog anions ntawm tib hom. Nyob rau hauv cov txheej txheem tsim no, ib qho dej molecule raug tshem tawm thaum lub sij hawm ua ke ntawm ob acids los yog anions. Qee cov piv txwv ntawm isopoly acids muaj xws li isopolychromate, isopolymolybdate, isopolytungstate, isopolyvanadate, isopolynobates, thiab lwm yam.
Piv txwv li, isopoly acids ntawm molybdenum cov ntaub ntawv thaum molybdenum trioxide yog yaj nyob rau hauv aqueous sodium hydroxide. Nws tuaj yeem tsim dimolybdate, trimolybdate, tetramolybdate, thiab lwm yam. Cov kua qaub no tsim los ntawm kev sib xyaw ntawm chav tsev yooj yim MoO 6Vim tias chav tsev yooj yim no muaj octahedral geometry, isopoly acidic compounds tsim los ntawm kev sib xyaw ua ke. ntawm ob lub ces kaum los yog ntug ntawm cov octahedral units. Txawm li cas los xij, qhov kev sib xyaw no uas tshwm sim los ntawm cov ces kaum ua rau muaj kev cuam tshuam ntawm Mo hlau atoms. Thiab, qhov kev tawm tsam no tuaj yeem txo qis siv lwm cov hlau, uas tsis yog molybdenum.
Heteropoly Acids yog dab tsi?
Heteropoly acids yog inorganic acidic compounds uas tsim los ntawm kev sib xyaw ntawm cov kua qaub los yog anions ntawm ntau hom. Feem ntau, cov kua qaub no yog kev sib txuas ntawm cov pa oxygen thiab hydrogen atoms nrog cov hlau tshwj xeeb thiab nonmetals. Cov kua qaub no tseem ceeb heev uas yog cov khoom siv rov siv tau hauv cov tshuaj lom neeg. Lawv muaj cov ntawv thov ua homogeneous thiab heterogeneous catalysts.
Daim duab 01: Heteropoly Acids yog Cov Txheej Txheem Teebmeem
Muaj ob peb yam uas peb yuav tsum tau kuaj ua ntej categorizing ib qho kua qaub li heteropoly acid. Nws yuav tsum muaj cov hlau (xws li tungsten, molybdenum, thiab lwm yam), oxygen atom (s), ib lub ntsiab ntawm p-block ntawm lub sij hawm lub sij hawm, thiab hydrogen atoms uas yog acidic. Cov hlau atoms hu ua addenda atoms. Muaj plaub hom heteropoly acids.
- 1:12 tetrahedral
- 2:18 tetrahedral
- 1:6 tetrahedral
- 1:9 tetrahedral
Tsis tas li ntawd, qee qhov piv txwv ntawm heteropoly acids suav nrog H3PW12O40, H6P2Mo18O62, thiab lwm yam.
Qhov txawv ntawm Isopoly thiab Heteropoly Acids yog dab tsi?
Y A poly acid yog ib qho acidic compound uas tsim los ntawm kev sib xyaw ntawm ob cov kua qaub los ntawm kev tshem tawm cov dej molecules. Qhov sib txawv tseem ceeb ntawm isopoly thiab heteropoly acids yog tias isopoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub zoo sib xws lossis anions whereas heteropoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub sib txawv lossis anions. Yog li ntawd, isopoly acids muaj tib qhov rov ua dua tab sis heteropoly acids muaj qhov sib txawv rov ua dua.
Piv txwv ntawm isopoly acids suav nrog isopolychromate, isopolymolybdate, isopolytungstate, isopolyvanadate, isopolyniobates, thiab lwm yam. Piv txwv ntawm heteropoly acids suav nrog H 3 PW 12 O40, H6P2Mo18 O62, thiab lwm yam.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm isopoly thiab heteropoly acids.
Summary – Isopoly vs Heteropoly Acids
A poly acid yog ib qho acidic compound uas tsim los ntawm kev sib xyaw ntawm ob cov kua qaub los ntawm kev tshem tawm cov dej molecule. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm isopoly thiab heteropoly acids yog tias isopoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub zoo sib xws lossis anions whereas heteropoly acids tsim los ntawm kev sib xyaw ntawm cov kua qaub sib txawv lossis anions.
