Gewinnung und Darstellung
Natriumhypobromit kann durch die Reaktion von Brom und Natriumhydroxid in Anwesenheit von Wasser hergestellt werden.cite-ref-handbook-of-preparative-inorganic-chemistry-1-3[1]

Das Vermischen einer LΓΆsung von Dibromoxid in Tetrachlormethan und Natriumhydroxid lΓ€sst auch das Salz entstehen.cite-ref-3[3]

Eigenschaften
Das Salz zerfΓ€llt bereits bei 0 Β°C innerhalb von zwei Tagen. Bei dieser Zersetzung entsteht Natriumbromid NaBr und Natriumbromat NaBrO3.cite-ref-handbook-of-preparative-inorganic-chemistry-1-4[1]
