NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide le paarọ rẹ nipasẹ gaasi chlorine lati fun bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide ṣe atunṣe pẹlu sulfuric acid ti o ni idojukọ lati ṣe ipilẹṣẹ bromine, eyini ni, labẹ iṣẹ ti oxidizing acid lagbara, iṣuu soda bromide le jẹ oxidized ati ofe lati bromine.
2NaBr+3H2SO4 (ti a kojọpọ) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide le fesi pẹlu dilute sulfuric acid lati gbejade hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Ni ojutu olomi, iṣuu soda bromide le fesi pẹlu awọn ions fadaka lati ṣe ina ofeefee bromide fadaka to lagbara.
Br - + Ag + = AgBr osi
6) Electrolysis ti iṣuu soda bromide ni ipo didà lati ṣe ina gaasi bromine ati irin iṣuu soda.
2 agbara nabr = 2 na + Br2
7) Sodium bromide aqueous ojutu le ṣe ina iṣuu soda bromate ati hydrogen nipasẹ electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Awọn aati Organic le waye, gẹgẹbi iṣesi akọkọ lati ṣe bromoethane:
