General

Synonyms:
Use: reagent
Molecular formula: Br2 dissolved in H2O (typically 3.6% bromine)
CAS No: n/a (CAS for bromine is 7726-95-6)
EC No:

Physical data

Appearance: amber liquid with a strong smell of bromine
Melting point:
Boiling point:
Vapour density:
Vapour pressure:
Density (g cm-3): typically 1.03
Flash point:
Explosion limits:
Autoignition temperature:
Water solubility: miscible in all proportions


Stability

Stable. Releases bromine to the air on standing. Slowly diminishes in strength when exposed to air and light. Incompatible with ammonia, some metals, phosphorus.

Toxicology

Harmful if ingested or inhaled. Prolonged skin contact can cause burns. Eye irritant - lengthy contact will lead to eye damage. Follow this link for further information about pure bromine.

呈橙色. 易挥发. 溴的蒸气红棕色。
移取液溴时,需戴橡皮手套。溴水的腐蚀性较液溴弱,在取用时不允许直接倒而要使用滴管。如果不慎把溴水溅在皮肤上,应立即用水冲洗,再用碳酸氢钠溶液或稀硫代硫酸钠溶液冲洗。

溴水呈 紅棕色,是溴的顏色。在水溶液 中溴與水作用產生無色的H+、Br-及HBrO(次溴酸)。在水溶液中,也可發生逆反應而保持平衡,
