Qhov sib txawv tseem ceeb ntawm aluminate thiab meta aluminate yog aluminate yog oxide anion, whereas meta aluminate yog hydroxide anion.
Aluminate thiab meta aluminate yog ob hom anions uas muaj feem xyuam rau ib leeg nyob ntawm lawv cov qauv tshuaj. Txawm li cas los xij, lawv atomicity txawv ntawm ib leeg. Qhov no yog vim hais tias aluminate anion tsuas muaj oxygen atoms nyob rau hauv koom nrog txhuas atoms, whereas meta aluminate muaj ob hydrogen thiab oxygen atoms nyob rau hauv koom nrog txhuas atoms.
Aluminate yog dab tsi?
Aluminate yog ib qho oxyanion ntawm txhuas muaj cov tshuaj formula AlO 4–Qhov sib xyaw ua ke uas muaj aluminate anion feem ntau yog sodium aluminate. Tsis tas li ntawd, ntshiab sodium aluminate yog ib qho khoom siv tsis muaj dej uas zoo li cov dawb crystalline khoom. Lub caij no, hydrated sodium aluminate tshwm sim raws li hydroxide compound. Thiab, feem ntau hydrated sodium aluminate daim ntawv yog tetrahydroxyaluminate ntawm sodium.
Daim duab 01: Pom ntawm Sodium Aluminate
Ntau dua, aluminate anion yog polyatomic anion uas muaj aluminium atom ntawm qhov chaw ntawm anion thiab plaub oxygen atoms txuas rau lub hauv paus txhuas atom ntawm covalent bonds. Tus nqi ntawm anion yog -1. Cov molar loj ntawm anion yog 91 g / mol.
Meta Aluminate yog dab tsi?
Meta aluminate yog daim ntawv hydrated ntawm aluminate anion. Yog li, aluminate yog oxyanion thaum meta aluminate yog hydroxide anion. Cov tshuaj formula ntawm no anion yog Al(OH)4– Tsis tas li, molar mass ntawm no anion yog 95 g / mol. Ntxiv mus, ib qho meta aluminate anion tsim thaum ob lub dej molecules tuaj koom nrog ib qho aluminate anion.
Daim duab 02: Cov Qauv Tshuaj ntawm Meta Aluminate Anion
Nquag, AlO2– ion hu ua "meta" hos AlO3 3- ion hu ua "ortho" compound. Lub ortho, para thiab meta conformations ntawm aluminate ions txawv ntawm ib leeg nyob ntawm qhov condensation degree. Lo lus "meta" yog hais txog qhov tsawg kawg nkaus hydrated daim ntawv ntawm sodium aluminate.
Qhov txawv ntawm Aluminate thiab Meta Aluminate yog dab tsi?
Aluminate thiab meta aluminate yog ob daim ntawv anionic ntsig txog. Qhov sib txawv tseem ceeb ntawm aluminate thiab hlau aluminate yog aluminate yog oxide anion, whereas meta aluminate yog hydroxide anion. Tsis tas li ntawd, cov tshuaj formula ntawm aluminate yog AlO4– thaum cov tshuaj formula ntawm meta aluminate yog Al(OH) 4 –
Ntxiv mus, lub aluminate anion yog oxyanion thaum lub meta aluminate yog hydrated oxyanion. Yog li, qhov no yog lwm qhov sib txawv ntawm aluminate thiab hlau aluminate. Tsis tas li ntawd, cov molar loj ntawm aluminate yog 91 g / mol, thaum molar loj ntawm meta aluminate yog 95 g / mol.
Nyob ntawm qhov muaj pes tsawg leeg, peb tuaj yeem hu rau aluminate ib qho oxyanion (muaj txhuas thiab oxygen atoms) thaum meta aluminate tuaj yeem categorized li hydroxyanion (muaj txhuas ua ke nrog oxygen thiab hydrogen atoms). Sodium aluminate yog ib qho piv txwv zoo ntawm cov khoom sib xyaw uas muaj cov aluminate anion thaum sodium meta aluminate yog ib qho piv txwv ntawm cov compound uas muaj cov meta aluminate anion.
Hauv qab infographic qhia txog qhov sib txawv ntawm aluminate thiab hlau aluminate.
Summary – Aluminate vs Meta Aluminate
Aluminate thiab meta aluminate yog ob daim ntawv anionic ntsig txog. Qhov sib txawv tseem ceeb ntawm aluminate thiab hlau aluminate yog aluminate yog oxide anion, whereas meta aluminate yog hydroxide anion. Yog li, aluminate hu ua oxyanion thiab meta aluminate hu ua hydroxyanion. Cov tshuaj formula ntawm aluminate anion yog AlO4– thaum cov tshuaj formula ntawm meta aluminate anion yog Al(OH) 4 –
