Lintho tsa lik'hemik'hale
1) Anhydrous sodium bromide crystals precipitate ka sodium bromide solution at 51 ℃, and dihydrate e thehoa ha mocheso o le tlase ho 51℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Bromide ea sodium e ka nkeloa sebaka ke khase ea chlorine ho fana ka bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide e sebetsana le concentrated sulfuric acid ho hlahisa bromine, ke hore, tlas'a ketso ea acid e matla ea oxidizing, bromide ea sodium e ka ba oxidized 'me ea lokolohile ho bromine.
2NaBr+3H2SO4 (e tsepamisitsoe maikutlo) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide e ka sebetsana le dilute sulfuric acid ho hlahisa hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Ka har'a tharollo e nang le metsi, sodium bromide e ka sebetsana le li-ion tsa silevera ho etsa bromide ea silevera e bosehla bo bobebe.
Br - + Ag + = AgBr ka ho le letšehali
6) Electrolysis ea sodium bromide boemong bo qhibilihisitsoeng ho hlahisa khase ea bromine le tšepe ea sodium.
2 nabr e matlafalitsoeng = 2 le + Br2
7) Tharollo ea metsi a sodium bromide e ka hlahisa bromate ea sodium le hydrogen ka electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Karabelo ea 'mele e ka etsahala, joalo ka karabelo e kholo ea ho etsa bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O
