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. See more Hydrogen iodide (HI) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. Hydrogen iodide and hydroiodic acid are, however, different in … See more The industrial preparation of HI involves the reaction of I2 with hydrazine, which also yields nitrogen gas: 2 I2 + N 2H 4 → 4 HI + N 2 When performed in … See more • Hydroiodic acid See more HI is a colorless gas that reacts with oxygen to give water and iodine.
