We can always contact bromine in different occasions in production and life. As an important extract of marine chemical raw materials, bromine solubility is the main factor related to bromine application. For the solubility of bromine, the following summary is made.
 
Bromide has such a large application in the industry because bromine can form bromide, and the bromide produced is widely used in various industries. In order to better carry out bromide production, the following properties for bromine need to be carried out. explain.
Bromine is soluble in water and ether, carbon disulfide, carbon tetrachloride, chloroform, kerosene and other organic solvents. The solubility of bromine in 95% sulfuric acid at 25 ° C is different at different temperatures and bromine solubility. 0.75%. The solubility of water in bromine at 22 ° C was 0.046%.
The saturated aqueous solution of bromine contains 3.22 - 3.41% bromine at a pressure of 105 Pa and a temperature range of 20 to 50 °C. When the temperature is lower than 5.84 ° C, Br 2 · 8H 2 O is precipitated from the aqueous solution.
Regarding the solubility of bromine, it is important to note that sulphate and nitrate reduce the solubility of bromine in water, while chlorides and sulphides increase it.
 
Bromine in sales. Generally liquid bromine, that is, bromine water, an aqueous solution of bromine, has a brownish yellow color and does not freeze at -20 °C. The vapor pressure of liquid bromine was 8786 Pa at 0 °C, 23064 Pa at 26 °C, and 52262 Pa at 40 °C. The vapor pressure of bromine on the aqueous solution of bromine follows Henry-Dalton's law (taking into account the amount of hydrolyzed bromine or the hydrolysis of bromine is inhibited).
