Preparation of Iodine monochloride: this reaction entails simply combining the halogens in a 1:1 molar ratio, according to the following equation. When chlorine gas is passed through iodine crystals, the brown vapor of iodine monochloride is observed. Dark brown iodine monochloride liquid is collected.

I₂ + Cl₂ → 2 ICl
