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»
Those salts dissolve into potassium or sodium ions and iodine ions. The iodine ion (I-) reacts with the free iodine (I 2) to form a triiodide ion (I 3-) which is soluble in water and can react with glucose chains.
