Chemical Compounds Bromine The element Bromine, is a red liquid which is explosive at room temperature and has a red brown vapour. It has an atomic number of 35 and an atomic mass of 79.909. The melting point of Bromine is -7 deg.C and the boiling point is 58 degC with a relative density of 3.1. Bromine is a volatile dense mobile, that is a reddish brown liquid, which quickly gives a brown toxic valour with a disagreeable irritating odour.
It combines directly with most elements although heat or a reactant is often neccessary to start some reactions. Hydrobomic Acid and Hypobromous Acid is a mixture that is formed when Bromine reacts with water.Oxygen is liberated by Bromine when the resulting solution is heated or exposed to strong sunlight. A solution to Bromine in water is called Bromine Water, which is used as a test reagent in organic chemistry to identify unsaturated compounds. Bromine resembles Chlorine in many of its properties, but is less active. Because of its reactivity, Bromine does not exist in the free elemental state in nature, but small quantities are combined in many silver ores. Bromine salts are found in seawater and in the salts deposits in Strassfurt.
Compounds of Bromine also occurs in marine animals and plants. Bromine is used in a wide range of industries.It is used in the manufacture of 1,2-DibromoEthane, CH2BrCH2Br, which is used as a petrol additive to prevent lead being deposited in the cylinders. The manufacture of compounds used in photography and the manufacture of dyestuffs and drugs is another use of bromine.
Bromine is used in the analytical laboratory in testing for unsaturation in organic compounds, where it adds across the multiple bonds of unsaturated compounds. Science Essays.
