Uses of Bromine
Some major uses of bromine have been discussed below:
- Bromine is a good oxidising agent like other chlorine water and is more useful as it does not decompose readily.
- It also liberates free iodine from iodide- containing solutions and sulphur from hydrogen sulphide.
- Sulphurous acid is oxidised to sulphuric acid by bromine water.
Properties Of Bromine
- The electron affinity of this metal is very high and much similar to the chlorine.
- It is a less powerful oxidising agent as compared to the chloride ion and that too because of weaker hydration of the bromide ion.
- The electron affinity of this metal is very high and much similar to chlorine.
- It is a less powerful oxidising agent as compared to the chloride ion and that too because of weaker hydration of the bromide ion.
- A metal-bromine bond is also weaker than the corresponding metal-chlorine bond.
Certain Facts About Bromine
- This element is bleach and is poisonous in fluid form, the vapours of it are dangerous for human skin, eyes, and the respiratory tract.
- It can also cause severe burns, a concentration of 1 ppm can lead to eye-watering and one can start to cough when inhalation of concentration below 10 ppm occurs.
