Final answer:
The accurate statements about halogen displacement reactions involve the reactivity series, observations during reactions, and the color change in solutions.
Explanation:
The correct statement about halogen displacement reaction:
- A more reactive Halogen can displace a less reactive halogen ion from their salt in solution. This is based on the reactivity series where a more reactive halogen can displace a less reactive halogen from its compound.
- You can recognize a halogen displacement reaction by the solution fizzing during the reaction. Fizzing often indicates a chemical reaction is happening.
- It is not the halogen ion that provides the color to the solution, but it is the resulting compound after the reaction that may exhibit color.
