Iodine chloride (also iodine monochloride ) is an interhalogen compound , which consists of the elements iodine and chlorine . It was discovered in 1814 by Humphry Davy and also independently by Gay-Lussac .
Extraction and presentation
Iodine chloride can be made from the elements or by boiling iodine in aqua regia .
Iodine chloride decomposes in water to form hydrogen chloride , iodic acid and iodine. The solid α-form has a pungent smell and is not very hygroscopic , it forms ruby-red needles. The metastable β-form is in the form of brown-red, rhombic panels.
Iodine chloride is generally corrosive ; the vapors / aerosols cause coughing, dyspnoea and irritation of the mucous membranes. The lowest known lethal dose is 50 mg / kg body weight orally in rats, or 500 mg / kg when absorbed through the skin .
