Why the unsaturated compound decolourises with bromine?
Unsaturated compounds decolorize bromine because bromine is added across the double bond through an electrophilic addition reaction. This reaction converts the orange bromine solution to a colorless product, resulting in decolorization of the solution.
When chlorine is added to sodium bromide solution one of the products is bromine?
When chlorine is added to sodium bromide solution, bromine is produced as one of the products through a redox reaction. The chlorine oxidizes the bromide ion to form bromine gas, while itself being reduced. This reaction is used to synthesize bromine from sodium bromide.
What is the source of bromine?
Bromine is extracted from brine pools, which are large bodies of water that contain high concentrations of dissolved salts. It is typically found in underground reservoirs and extracted through a process called solution mining. Additionally, bromine can also be found in some minerals like brucite and carnallite.
What color change occurs when chlorine gas is passed through a solution of potassium bromide?
When chlorine gas is passed through a solution of potassium bromide, the solution will change from colorless to yellow. This indicates the formation of elemental bromine as a result of the reaction between chlorine and bromide ions.
Do chlorine and potassium bromine react?
Yes, the reaction is:Cl2 + 2 KBr = 2 KCl + Br2

Does pentene decolourise bromine solution?
Pentene is an unstaturdated hydrocarbon (One that does not have many possible side branches) It reacts readily with halogens to form new substances. In this case, bromine reacts with pentene in an addition reaction, this changes pentene into 1,1-dibromopentane. Thus, removing bromine from the solution, hence the distinct orange color is removed.
When chlorine is added to sodium bromide solution one of the products is bromine?
When chlorine is added to sodium bromide solution, bromine is produced as one of the products through a redox reaction. The chlorine oxidizes the bromide ion to form bromine gas, while itself being reduced. This reaction is used to synthesize bromine from sodium bromide.
Where is bromine found or mined?
Bromine is found naturally in underground brine wells, primarily in the United States and Israel. It is extracted through a process called solution mining, where the brine is pumped to the surface and evaporated to yield a concentrated bromine solution.
What products would you get when you bubble chlorine gas through a sodium bromide solution?
You would get Sodium Chloride and Bromine. This is because Chlorine is a more reactive group 7, (halogen), element that bromine, we know this because it is above bromine in the periodic table group, it is therefore more electronegative. When the reaction occurs, the Chlorine displaces the Bromine and the solution turns brown.
When fluorine gas is bubbled through a solution of sodium bromide the products are free bromine liquid and sodium fluoride in solution is?
The chemical reaction is: 2NaBr + F2 = 2NaF + Br2
Chlorine Gas is bubbled through a calcium bromide Solution what type of reaction is made?
Chlorine is a more reactive halogen than bromine, therefore, when chlorine gas is bubbled through a calcium bromide solution, the chlorine will take the place of the bromine. This is called an anionic single replacement (displacement) reaction. Cl2(g) + CaBr2(aq) --> Br2(l) + CaCl2(aq)

Does hexane and bromine water and sodium hydroxide solution react?
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
What color change occurs when chlorine gas is passed through a solution of potassium bromide?
When chlorine gas is passed through a solution of potassium bromide, the solution will change from colorless to yellow. This indicates the formation of elemental bromine as a result of the reaction between chlorine and bromide ions.
Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
How do you remove carbon tetrachloride from water?
Carbon tetrachloride can be removed from water through methods such as air stripping, activated carbon adsorption, or advanced oxidation processes. These techniques help to volatilize, adsorb, or break down the carbon tetrachloride, making the water safe for use or disposal. It is important to follow proper guidelines and regulations when handling and treating contaminated water.
