halogen displacement reactions 

a more reactive halogen will displace a less reactive one 

its when a more reactive element pushes out a less reactive one from a compound 

for example: chlorine is more reactive than bromine, if you add chlorine water to pottasium bromide solution, the chlorine will displace the bromine from the salt solution, the chlorine is reduced to chloride ions, so the salt solution becomes pottasium chloride. the bromide ions are oxidised to bromine, which turns the solution orange. 

chlorine+ pottasium bromide= pottasium chloride+bromine 

diplacement reactions show reactivity trends     …
