halogen displacement

Question 1

halogen displace reactions are ____ reactions, meaning?

Answer 1

redox, meaning the halogens gain electrons, whilst halide ions lose electrons (oxidation)

Question 2

example. if you add chlorine water to potassium bromide, what happens?

Answer 2

the chlorine will displace the bromine from the salt solution (as its more reactive), and the salt solution becomes potassium chloride

the bromide ions are oxidised to bromine, and so the solution becomes orange
