Kayan aikin sinadarai
1) Anhydrous sodium bromide lu'ulu'u suna haɗuwa a cikin maganin sodium bromide a 51 ℃, kuma ana samun dihydrate lokacin da zafin jiki ya ƙasa da 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Za'a iya maye gurbin sodium bromide da sinadarin chlorine domin bada bromine.
2Br- + Cl2 = Br2 + 2Cl-
3) Sodium bromide yayi tasiri tare da maida hankali ga sulfuric acid don samar da bromine, ma’ana, a karkashin aikin karfi na saka sinadarin acid, sodium bromide za a iya sanyashi kuma ba tare da shi ba.
2NaBr + 3H2SO4 (mai da hankali) = 2NaHSO4 + Br2 + SO2 ↑ + 2H2O
4) Sodium bromide na iya yin aiki tare da narkar da sanadarin sulfuric don samar da hydrogen bromide.
NaBr + H2SO4 = HBr + NaHSO4
5) A cikin bayani mai ruwa-ruwa, sodium bromide na iya amsawa tare da ions na azurfa don samar da haske mai haske rawaya azurfa bromide.
Br - + Ag + = AgBr ya bar
6) Electrolysis na sodium bromide a cikin narkakken yanayi don samar da iskar bromine da sinadarin sodium.
2 an kunna nabr = 2 na + Br2
7) Magungunan ruwa na sodium bromide na iya samarda sinadarin sodium bromate da hydrogen ta hanyar electrolysis.
NaBr + 3H2O = wutar lantarki NaBrO3 + 3H2 electro
8) Hanyoyin jiki na iya faruwa, kamar babban abin da akeyi don yin bromoethane:
