Sodium hypobromite , NaBrO, is a chemical compound of sodium from the group of hypobromites .

Extraction and presentation

Sodium hypobromite can be produced by the reaction of bromine and sodium hydroxide in the presence of water .

${\displaystyle {\ce {Br2 + 2 NaOH + 4 H2O -> NaBrO*5 H2O + NaBr}}}$

Mixing a solution of dibromine oxide in carbon tetrachloride and sodium hydroxide also creates the salt.

${\displaystyle {\ce {Br2O + 2 NaOH -> 2 NaBrO + H2O}}}$

properties

The salt disintegrates within two days at 0 ° C. This decomposition produces sodium bromide NaBr and sodium bromate NaBrO ₃ .
