bromine water is diluted with water bromine.Its in equations reaction is usually written by a formula - Br2, although it is in solution in a mixture of two acids - HBrO (hypobromous acid) and HBr (hydrobromic acid).This compound has a yellow-orange color and is quite a low freezing point.Is a strong oxidant which is capable under alkaline conditions to oxidize cations such metals - Cr + 3, Mn + 3, Fe + 2, Co +2, Ni + 3.Adding Br2 reduces the pH value (pH), sincebromine water contains free acid.
It is chemically active substance which can interact with both inorganic and organic substances.Consider some of the chemical processes with the connection.
discoloration of bromine water is a high-quality response to all unsaturated hydrocarbons.To conduct this experiment you need a small amount of an alkene or alkyne all mixed in a test tube with Br2.During this reaction, the attaching of the bromine atoms in place of discontinuity double or triple bond.The disappearance of the yellow-orange color when such interaction is proof unsaturation taken hydrocarbon.
chemical reaction "phenol - bromine water" is used for the deposition of solutions of brominated compounds.If the interaction of agents to carry out under anhydrous conditions, the formation of tribromophenol takes a couple of days.Therefore, as the catalyst a small amount of H2O.
bromine water in a laboratory prepared as follows: to 1 ml of bromine was added 250 ml of distilled water while vigorously stirring.The mixed solution was stored in a tightly closed container made of dark glass.If prepared Br2 stored in the light or light in a flask that oxygen evolution will occur because of the content of hypobromous acid.Work on the preparation of the reagent is carried out in a fume hood.Since very toxic bromine and bromine water it contains, while working with her to be careful.
is necessary to take into account the fact that the Br2 in contact with skin appears intense itching, and prolonged exposure can cause ulcers.If the material gets on your skin, it should be rinsed with plenty of water, and then sodium carbonate.When a large wound surface or deep skin lesions epidermis further lubricated with ointment, which includes NaHCO3.
bromine water is widely used in chemical analysis and synthesis of organic products.Thus, its use in the production of bromine-containing drugs.And here it is necessary to be careful, becausetheir prolonged use can lead to disease - bromism.The main symptoms - lethargy, fatigue, skin rash.For a more rapid elimination of bromide ions from the body dieting with a high content of salt and drink plenty of liquids.More bromine water used in the intermediate stages of production of flame retardants - substances that protect organic compounds from the ignition.They impregnated fabric, wood, building material.
