Question

Which one will liberate Br₂ from KBr?

पर्याय

• H₂

• I₂

• Cl₂

• SO₂

Answer 1

Cl₂

Explanation:

Chlorine (Cl₂) is more reactive than bromine (Br₂) and lies above it in the halogen reactivity series. Therefore, chlorine can displace bromine from potassium bromide solution.

\[\ce{Cl2 + 2KBr -> 2KCl + Br2}\]
