Description of key information
HBr is very soluble in water, with solutions of HBr in water forming hydrobromic acid which dissociates to ions (H+and Br-). It
forms an azeotropic mixture in water of 47.63% with boiling point of 124.3 at 760 mm Hg. A saturated solution is 66.5% at 25ºC.
Key value for chemical safety assessment
- Water solubility:
- 665 g/L
- at the temperature of:
- 25 °C
Additional information
Garlanda, T., and Basilico, S. (1993) report HBr as very soluble in water, forming an azeotropic mixture in water of 47.63 % with boiling point of 124.3 ºC at 101323 Pa (760 mm Hg). A saturated solution occurs at 66.5 % at 25 ºC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
