What would you observe if astatine solution is added to sodium bromide solution?
There would be no reaction because astatine is less reactive than bromine.
What would be observed if chlorine water was added to a dilute solution of sodium bromide?
Chlorine will displace bromine from NaBr
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
What happens when the bromine solution is first added to cyclohexane?
At room temperature, the halogens like bromine don't react with cyclohexane. Hence the dark brown color of the bromine water remains. When heated, the -H atoms are replaced with -Br(substitution reaction).
What happens when bromine water is added to paraffin?
the solution decolourised
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."
What happens when bromine water is added to ethanol?
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
What would you observe if astatine solution is added to sodium bromide solution?
There would be no reaction because astatine is less reactive than bromine.
Which reaction occurs when bromine is added to an aqueous solution of iodide ions?
2I- + Br2 ---> I2 + 2Br-
What happens when a drop of water is added to calcium carbide in the presence of bromine solution?
Probable tetrabromoethane is formed.
What would be observed if chlorine water was added to a dilute solution of sodium bromide?
Chlorine will displace bromine from NaBr
What will happen if a highly concentrated substance is added to a solution?
It will gradually diffuse until it reaches equilibrium.
Is bromine a solution?
NO!!! Bromine is an element, which exists in the liquid state at STP.

The solution will turn the orange bromine water into a colourless solution

Which solution tests for sugar?
Bromine
