What is Bromine?

  • Bromine is a chemical element with the appearance of a deep red, noxious liquid being one of the members of the halogen elements of the periodic table.
  • This element has an appreciable vapor pressure at room temperature.

Uses Of Bromine

  • Bromine is a good oxidizing agent like other chlorine water and more useful as it does not decompose readily.
  • It also liberates free iodine from iodide- containing solutions and sulfur from hydrogen sulfide.
  • Sulfurous acid is oxidized to sulfuric 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 oxidizing 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 the chlorine.
  • It is a less powerful oxidizing 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 a bleach and is poisonous in fluid form, the vapors 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.
