Is bromine a solution?
NO!!! Bromine is an element, which exists in the liquid state at STP.
What happens if ethene is shaken with bromine water?
The solution will turn the orange bromine water into a colourless solution
Why does alkyne decolourise bromine water?
The alkyne reacts with bromine removing it from the aqueous solution.
Is bromine a mixture?
Bromine is an element, and therefore a pure substance, not a mixture. However, sometimes people loosely refer to bromine water (a solution of bromine in water) as just bromine.
What kind of reaction takes place when butene decolourises bromine solution?
an addition reaction takes place when butene decoulourises bromine solution x
Where you get bromine from?
Bromine is prepared by a method which comprises contacting hydrogen peroxide with an aqueous solution containing bromide ion and rapidly removing the bromine as it is formed. This method is particularly suitable for obtaining bromine from seawater, using the conventional intermediate, bromosulfuric solution.

What is bromine and carbon tetrachloride?
Bromine in carbon tetrachloride is a brown-colored solution and used as a chemical test. When drops of bromine/carbon tetrachloride are added to a solution containing an unknown compound and the brown-colored bromine solution disappears, that means that the unknown compound contains carbon-carbon double bonds (since it absorbed the bromine solution). On the other hand, if the brown-colored bromine solution doesn't disappear then it means that no carbon double bonds are present. This is called a "Bromine Test."

Why bromine solution added gradually?
Add the bromine solution slowly and with constant shaking to ensure thorough mixing; stand the flask in cold water
How do you prepared Hanus solution?
Add 13.2g of Iodine ( resublimed) to 1 liter of glacial acetic acid ( 99.5 %) pure. Heat lightly to dissolve Iodine. Cool the solution and add 3 ml of bromine solution to it ( to increase the halide percentage). Store the hanus solution in a Amber bottle and away from light. The Hanus solution can be used for a year.
What result occurs adding ethyl cyclohexene to Bromine?
Cyclohexene picks up the bromine from solution and becomes dibromoethylcyclohexane.
When was bromine discovered?
Discovered by Balard in 1826, but not prepared in quantity until 1860.
