4.2.2 Halogen displacements Flashcards
1
Q
What is halogen displacement?
A
More reactive halogens can displace less reactive halogens from their compounds.
2
Q
Why are halogen displacement reactions redox reactions?
A
The more reactive halogen takes an electron from the halide ion in the salt.
3
Q
Why are there colour changes in halogen displacement reactions?
A
The colour change is due to the halogens present because the salts are all colourless.
