: At ambient temperature bromine is a brownish-red liquid. It has a similarly colored vapor with an offensive and suffocating odor. It is the only nonmetallic element that is liquid under ordinary conditions, it evaporates easily at standard temperature and pressures in a red vapor that has a strong disagreeable odor resembling that of chlorine. Bromine is less active chemically than chlorine and fluorine but is more active than iodine; its compounds are similar to those of the other halogens. Bromine is soluble in organic solvents and in water.the properties of bromine are as follows:
Atomic Number : 35
Atomic mass : 79.904
The Melting point : -7.2
The Boiling point : 58.8
The Physical Properties of Bromine
Being less reactive than chlorine but more reactive than iodine, bromine reacts vigorously with metals, especially in the presence of water, to give bromide salts. It is also reactive toward most organic compounds, especially upon illumination, conditions that favor the dissociation of the diatomic molecule into bromine radicals:
Bromine can be found in different formats such as : seawater,pesticides,plastics,water purification,medicine and photography.
The advantages of bromine such as :
- 95 percent of Br2 produced, used in the preparation, and ethylene bromide 1 2-dibromoethane (or ethylene dibromide). For use as a filler in oil, gasoline, gasoline have sought a mountain high. (in conjunction with tetra ethyl lead).
- Used as a precursor in the preparation of chemicals, both organic and inorganic components with Br.
- Bromine part sold in the form of a liquid. Use of a drug in analysis and synthesis.
-And etc.
The disadvantages of bromine such as :
- Health effects of bromine
: Bromine is corrosive to human tissue in a liquid state and its vapors irritate eyes and throat. Bromine vapors are very toxic with inhalation.
Humans can absorb organic bromines through the skin, with food and during breathing. Organic bromines are widely used as sprays to kill insects and other unwanted pests. But they are not only poisonous to the animals that they are used against, but also to larger animals. In many cases they are poisonous to humans, too.
The most important health effects that can be caused by bromine-containing organic contaminants are malfunctioning of the nervous system and disturbances in genetic materials.
But organic bromines can also cause damage to organs such as liver, kidneys, lungs and milt and they can cause stomach and gastrointestinal malfunctioning. Some forms of organic bromines, such as ethylene bromine, can even cause cancer. Inorganic bromines are found in nature, but whereas they occur naturally humans have added too much through the years. Through food and drinking water humans absorb high doses of inorganic bromines. These bromines can damage the nervous system and the thyroid gland.
