Qhov kev ncua deb ntawm bromine atom thiab lub hauv paus oxygen atom yog deb tshaj li ob lub atoms oxygen.
5. Molecular zog:
Sodium bromate muaj qee qhov tshwj xeeb molecular zog. Nws yog cov khoom tsis muaj xim, tsis muaj ntxhiab tsw uas tuaj yeem yaj hauv dej. Cov tshuaj no muaj oxidizing zog thiab tuaj yeem decompose los tsim cov pa oxygen hauv cov cua sov.
Lub npe niaj hnub ntawm Sodium bromate pib thaum xyoo 19th txog rau thaum ntxov xyoo pua 20th, thaum cov kws tshawb fawb tau tshawb fawb ntau yam ntawm cov tshuaj uas muaj cov ntsiab lus bromine.
Thaum ntxov, tom qab kev tshawb pom ntawm bromine, chemists pib tshawb nws cov tebchaw. Bromic acid yog ib hom bromine compound nrog cov tshuaj formula HBrO3, qhov twg H yog hydrogen keeb, Br yog bromine keeb, thiab O yog cov pa oxygen. Bromic acid muaj zog oxidizing zog thiab yog ib tug muaj zog acid, yog li cov kws tshawb fawb tau pib kawm nws cov ntsev tebchaw.
Hauv cov txheej txheem ntawm kev kawm bromate, cov kws tshawb fawb pom tau tias sodium bromate yog ib qho oxidizing heev uas tuaj yeem oxidize lwm yam tshuaj nyob rau hauv acidic tej yam kev mob. Yog li, sodium bromate tau siv dav hauv thaj chaw xws li oxidants thiab tshuaj dawb.
Yuav kom piav qhia tau zoo dua cov khoom thiab kev siv ntawm sodium bromate, cov kws tshawb fawb tau pib npe nws. Xav tias sodium bromate yog tsim los ntawm sodium thiab bromate ions, lawv tau txais lub npe "sodium bromate". Ntawm lawv, "sodium" sawv cev rau cations hauv ntsev, thiab "bromate" sawv cev rau anions hauv ntsev.
Sij hawm dhau mus, lub npe "sodium bromate" maj mam tau txais dav thiab siv, thiab dhau los ua tus qauv lub npe rau qhov sib xyaw no. Txawm hais tias sodium bromate tseem hu ua sodium bromide hauv qee cov ntaub ntawv, lo lus 'sodium bromate' feem ntau siv.
Nyob rau hauv luv luv, lub hauv paus chiv keeb ntawm lub npe "sodium bromate" tuaj yeem taug qab rov qab mus rau lub xyoo pua 20th, thaum cov kws tshawb fawb pib kawm cov tebchaw ntawm bromine thiab pom tias sodium bromate muaj oxidation tsis kam thiab siv. Sij hawm dhau mus, lub npe "sodium bromate" maj mam tau txais dav thiab siv, dhau los ua tus qauv lub npe rau qhov sib xyaw no.

Sodium bromate muaj cov tshuaj tiv thaiv nyob rau hauv sulfuric acid thiab tej zaum yuav ua rau combustion. Yog li ntawd, kev sib cuag nrog sulfuric acid yuav tsum tau zam thaum siv sodium bromate.
Hauv cov ntsiab lus, cov khoom muaj zog oxidizing ntawm sodium bromate pab kom nws koom nrog ntau yam tshuaj lom neeg. Thaum siv sodium bromate, yuav tsum tau them nyiaj rau kev nyab xeeb thiab tsis txhob sib cuag nrog cov khoom tsis sib xws. Nyob rau tib lub sijhawm, kev nkag siab txog cov tshuaj tiv thaiv ntawm sodium bromate pab kom nkag siab zoo dua thiab siv nws txoj kev siv.
