Hydrogen halides as acids - chemguide
WebPotassium iodide solution, 0.25 mol dm –3, but the concentration is not critical, 100 cm 3; Starch solution, 20 cm 3; ... This is caused by the discharge of H + ions as hydrogen, which leaves an excess of OH-ions in the solution. This alkaline solution turns the … 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. With moist air, HI gives a mist (or fumes) of hydroiodic acid. It is … See more Solutions of hydrogen iodide are easily oxidized by air: 4 HI + O2 → 2 H 2O + 2 I2 HI + I2 ⇌ HI3 HI 3 is dark brown in color, which makes aged solutions of HI … See more • International Chemical Safety Card 1326 See more small bathroom corner storage
