Chlorine Displacing Bromine from Sodium Bromide

Cl2 + 2NaBr → 2NaCl + Br2

Genel Bakış

Chlorine gas displaces bromine from sodium bromide solution because chlorine is a stronger oxidizing agent than bromine. The colorless solution turns orange-brown as molecular bromine is liberated. This demonstrates the halogen displacement series.
