Qhov sib txawv tseem ceeb ntawm sodium aluminate thiab sodium meta aluminate yog sodium aluminate yog ib qho oxide compound, whereas sodium meta aluminate yog hydroxide compound.
Sodium aluminate yog ib qho inorganic compound. Nws yog ib qho oxide uas muaj sodium cations ua ke nrog txhuas oxide anions. Cov tshuaj no tseem hu ua sodium ortho aluminate. Sodium meta aluminate, ntawm qhov tod tes, yog ib qho derivative ntawm sodium aluminate.
Sodium Aluminate yog dab tsi?
Sodium aluminate yog ib qho tshuaj inorganic compound uas muaj cov tshuaj formula NaAlO2. Cov tshuaj lom neeg no muaj txiaj ntsig zoo hauv ob qho tib si hauv kev lag luam thiab kev kuaj sim ua qhov chaw tsim khoom ntawm sodium hydroxide.
Daim duab 01: Sodium Aluminate
Ntshiab sodium aluminate yog ib qho chaw tsis muaj dej uas zoo li cov dawb crystalline khoom. Lub hydrated sodium aluminate tshwm sim raws li hydroxide compound; Feem ntau hydrated sodium aluminate daim ntawv yog tetrahydroxyaluminate ntawm sodium. Nws cov tshuaj formula yog NaAl(OH)4 Cov anhydrous sodium aluminate muaj cov qauv ntawm 3D lub moj khaum uas muaj AlO 4tetrahedra nrog cov fab txuas rau ib leeg..
Peb tuaj yeem tau txais cov khoom lag luam muaj sodium aluminate nyob rau hauv daim ntawv ntawm cov tshuaj los yog ua cov khoom sib xyaw. Cov khoom no yog hygroscopic heev. Thaum sodium aluminate yaj hauv dej, nws muab cov xim dub xim colloidal tov. Sodium aluminate tsis muaj ntxhiab tsw.
Peb tuaj yeem tsim cov sodium aluminate los ntawm kev tawg ntawm aluminium hydroxide hauv caustic soda. Siv cov concentrated caustic soda tov ua cov khoom semi-solid. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tseeb concentration xav tau rau cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv yog nqa tawm nyob rau hauv cov hlab ntsha ua los ntawm npib tsib xee los yog hlau uas yog steam-rhuab.
Muaj ntau qhov tseem ceeb ntawm kev siv cov tshuaj sodium aluminate: hauv cov dej kho dej rau cov dej softening, kom nrawm nrawm hauv kev tsim kho, hauv kev lag luam ntawv, hauv hluav taws cib tsim, alumina ntau lawm, thiab lwm yam.
Sodium Meta Aluminate yog dab tsi?
Sodium meta aluminate yog daim ntawv hydrated ntawm sodium aluminate. Yog li ntawd, sodium meta aluminate feem ntau tshwm sim nyob rau hauv daim ntawv ntawm hydroxide. Peb hu ua sodium tetrahydroxide. Qhov no yog vim nws muaj cov tshuaj formula NaAl(OH)4 Daim ntawv anhydrous ntawm no compound yog sodium aluminate.
Daim duab 02: Cov qauv tshuaj ntawm Tetrahydro Aluminate Ion. Cov ion no, ua ke nrog sodium cation, tsim sodium meta hydroxide compound.
Sodium meta aluminate cov ntaub ntawv thaum ob lub dej molecules cuam tshuam nrog sodium aluminate chemical compound. Yog li ntawd, nws yog ib daim ntawv dihydrated. Nquag, AlO2– ion yog hu ua "meta" thaum 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 Sodium Aluminate thiab Sodium Meta Aluminate yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sodium aluminate thiab sodium meta aluminate yog sodium aluminate yog ib qho oxide compound, whereas sodium meta aluminate yog hydroxide compound. Cov tshuaj formula ntawm sodium aluminate yog NaAlO 2 thaum cov tshuaj formula ntawm sodium meta aluminate yog NaAl(OH) 4 Sodium meta aluminate yog qhov tseeb derivative ntawm sodium aluminate.
Hauv qab infographic tabulates qhov sib txawv ntawm sodium aluminate thiab sodium meta aluminate.
Summary – Sodium Aluminate vs Sodium Meta Aluminate
Sodium aluminate yog ib qho tshuaj inorganic compound uas muaj cov tshuaj formula NaAlO2 Sodium meta aluminate yog ib qho derivative ntawm sodium aluminate. Qhov sib txawv tseem ceeb ntawm sodium aluminate thiab sodium meta aluminate yog sodium aluminate yog ib qho oxide compound, whereas sodium meta aluminate yog hydroxide compound.
