Hydrogen iodide is a chemical compound composed of hydrogen and iodine. Its chemical formula is HI. It is a colorless, corrosive gas that has a pungent odor. Hydrogen iodide is a strong acid, which means it dissociates completely in water to form H+ ions and iodide ions (I-). It is used in various industrial processes such as the production of pharmaceuticals, catalysts, and semiconductors. Hydrogen iodide also plays a role in organic chemistry as a reagent for various reactions such as iodination, dehydrohalogenation, and hydroiodination. It is also used in the production of iodine supplements and disinfectants.
