Chemical properties
An anhydrous sodium bromide crystal is precipitated in the sodium bromide solution at 1.51 ° C, and a dihydrate is formed below 51 ° C.
NaBr+2H2O=NaBr·2H2O (T<51oC)
2. Sodium bromide can be replaced by chlorine gas to remove bromine.
2Br-+Cl2=Br2+2Cl-
3. Sodium bromide reacts with concentrated sulfuric acid to form bromine. Under the action of strong oxidizing acid, sodium bromide can be oxidized to release bromine.
2NaBr+3H2SO4 (concentrated) = 2NaHSO4+Br2+SO2↑+2H2O
4. Sodium bromide can react with dilute sulfuric acid to form hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5. In aqueous solution, sodium bromide can react with silver ions to form a pale yellow solid silver bromide.
Br-+Ag+=AgBr↓
6. Electrolytic molten sodium bromide forms bromine gas and sodium metal.
2NaBr=energized 2Na+Br2↑
7. The sodium bromide aqueous solution can be electrolyzed to produce sodium bromate and hydrogen.
NaBr + 3H2O=electrolytic NaBrO3 + 3H2↑
8. An organic reaction can occur, such as the main reaction for the preparation of ethyl bromide:
NaBr+H2SO4+CH2CH2OH⇌NaHSO4+CH3CH2Br+H2O
