Borax , kuj hu ua sodium borate , sodium tetraborate, los yog disodium tetraborate, yog ib qho tseem ceeb boron compound, ntxhia, thiab ntsev ntawm boric acid. Hmoov borax yog dawb, muaj cov xim mos mos uas yaj hauv dej.

Thiab cov lus nug yog, Borax puas tsim kev puas tsuaj rau tib neeg?

Nyob rau hauv tag nrho, borax yog tag nrho natural thiab tsis muaj inherently tshuaj lom cov khoom xyaw. Nws tsis ua rau mob qog noj ntshav, sib sau hauv lub cev lossis hauv qhov xwm txheej, lossis nqus los ntawm daim tawv nqaij. Vim koob tshuaj ua rau muaj tshuaj lom, borax tsis yog phom sij rau lub cev lossis ib puag ncig nrog ib txwm siv, siv sab nraud ntau dua li ntsev lossis ci dej qab zib.

Ib tug kuj nug, yog borate ib hlau? Ib tug naj npawb ntawm hlau borates paub. Lawv yog tsim los ntawm kev kho boric acid los yog boron oxides nrog hlau oxides. Piv txwv li nram qab no muaj xws li linear chains ntawm 2, 3 los yog 4 trigonal BO3 Cov chav nyob hauv cov qauv, txhua qhov sib koom tsuas yog ib qho oxygen atom nrog cov nyob ib sab:

Yog li ntawd, yog vim li cas borax raug txwv?

Txawm li cas los xij, FDA txwv tsis pub borax raws li a khoom noj khoom haus ntxiv, thiab European Chemicals Agency ntxiv nws rau lawv "cov npe ntawm cov khoom muaj kev txhawj xeeb heev" a ob peb xyoos dhau los. Lub siab alkalinity ntawm borax yog yuav ua li cas ua rau tawv nqaij khaus (xws li kev siv ntau tshaj ntawm baking soda yuav ua rau khaus).

Dab tsi yog borate ions?

PEB: 22909 - borate ua Ib qho inorganic anion uas yog tsim los ntawm boric acid. Lub sij hawm muaj xws li polymeric anions uas muaj chains ntawm BO3 Cov chav nyob sib koom ib qho oxygen atom (piv txwv li di-, tri-, thiab tetraborates) nrog rau cov chains lossis rings sib koom ob lub pa oxygen (piv txwv li metaborates).
