Question

Explain displacement reactions involving halogens

Answer 1

Answer:

Halogen displacement reactions are redox reactions because the halogens gain electrons and the halide ions lose electrons. When we consider one of the displacement reactions, we can see which element is being oxidised and which is being reduced.

Answer 2

Answer:

hope this helps u :-)

Explanation:

Halogen displacement reactions are redox reactions because the halogens gain electrons and the halide ions lose electrons. When we consider one of the displacement reactions, we can see which element is being oxidised and which is being reduced.A more reactive halogen can displace a less reactive halogen from solutions of its salts.

For example, chlorine is more reactive than iodine. A solution of chlorine can displace iodine from potassium iodide solution:

chlorine + potassium iodide → potassium chloride + iodine

Cl₂(aq) + 2KI(aq) → 2KCl(aq) + I₂(aq)
