WebHydrogen iodide, anhydrous appears as a colorless to yellow/brown gas with an acrid odor. Nonflammable. Toxic by inhalation. Strongly irritates skin, eyes and mucous membranes. Hydroiodic acid is not pure hydrogen iodide, but a mixture containing it. Commercial "concentrated" hydroiodic acid usually contains 48–57% HI by mass. The solution forms an azeotrope boiling at 127 °C with 57% HI, 43% water. The high acidity is caused by the dispersal of the ionic charge over the anion.
