Iodine monochloride is the chemical compound with the formula ICl. It is a red-brown compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, ICl is highly polar and behaves as a source of I+. Â»
An iodide ion is the ion I â . Compounds with iodine in formal oxidation state â1 are called iodides. This page is for the iodide ion and its salts, not organoiodine compounds.In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. Aqueous solutions of iodide salts dissolve iodine better than pure water.
