BRAINCAKEHalogen Displacement Reactions
Halogen displacement reactions are redox reactions where the more reactive halogen displaces the less reactive halide from its salt in solution.
Chlorine displaces bromide and iodide ions. Bromine displaces iodide ions.
Cl2(aq) + 2KBr(aq) → 2KCl (aq) + Br2(aq)
