· History. Bromine was discovered in 1826 by the French chemist Antoine-Jérôme Balard in the residues (bitterns) from the manufacture of sea salt at Montpellier. Because of the bad odour of the element, the French Academy of Sciences suggested the name bromine, from the Greek word bromos, meaning "bad smell" or "stench."

Bromine - Physico-chemical Properties. Characteristic red-brown fuming liquid. soluble in water, solubility of 3.58g/mL water (20 ° C); Soluble in ethanol, ether, chloroform, carbon tetrachloride, kerosene and carbon disulfide and other organic solvents; Also soluble in hydrochloric acid, hydrobromic acid and bromine compound solution.
Bromine isotopes Br-79 and Br-81 have great application sin the field of medicine. While Br-81 has been useful for diagnostic purposes, Br-79 is helpful in radiotherapy after getting decayed into the radioisotope Br-77. Another known fact about bromine isotopes is that most of them are results of fission.

· Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. The chemical symbol for Bromine is Br. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas.
· Bromine water, also called Bromide bromate solution or Bromine solution with the chemical formula Br 2. The molecular weight of bromine water is 159.81 and the density is 1.307 g/mL. Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br 2) in water (H 2 O).

The bromine story began with 24-year-old student Antoine-Jérôme Balard. He found that the salt residues left by evaporating brine from Montpellier, France, gave an oily red liquid when treated with acid. He realised this was a new element and reported it to the French Academy, who confirmed his discovery.
· Bromine is used to bleach flour.Iodine had been used for this purpose, but the people that care a lot about us decided to remove iodine and replace it with the potentially cancerous 1 version of a halogen, bromine. There are breads available that do not use bromine, but if the bread is white, it probably has bromine.
· History of bromine Two chemists, the German Carl Jacob Lowig and Frenchman Antoine Balard independently discovered bromine in the 19th century while studying natural salt waters. They crystallized the salts and saturated the remaining liquid with chlorine. What was left after distillation was a dark red liquid: bromine.

Bromine has strong bleaching properties, and is widely used as a disinfectant in swimming pools. It is also used for the manufacturing of fumigants, dyes, flameproof agents, water purification compounds and some medicines. It is also used in the production of Brominated vegetable oil, commonly used in soft drinks.
· The value of Bromine Index or Bromine Number expresses the trace amount of unsaturated constituents of hydrocarbons and oils. It is determined by measuring of consumed bromine for cleavage of double or multiple bounds during the titration. The value are needed for determination of parameters for further processing of petroleum products.
