Chlorine Oxidation of Bromide
Cl2 + 2Br− → 2Cl− + Br2
ภาพรวม
Chlorine oxidizes bromide ions to bromine while being reduced to chloride. This halogen displacement demonstrates the trend in oxidizing power: F₂ > Cl₂ > Br₂ > I₂. The reaction turns a colorless bromide solution orange-brown as molecular bromine is liberated.
