Chlorine Displacing Iodine from Potassium Iodide

Cl2 + 2KI → 2KCl + I2

نظرة عامة

Chlorine displaces iodine from potassium iodide solution because chlorine is more electronegative and a stronger oxidizer than iodine. The solution turns brown from the liberated iodine, which can be confirmed with starch indicator turning blue-black.
