What is the industrial preparation of hydrogen iodide?

The industrial preparation of HI involves the reaction of I 2 with hydrazine, which also yields nitrogen gas: 2 I 2 + N 2H 4 → 4 HI + N

How does hydrogen iodide react with active metals?

HYDROGEN IODIDE, [ANHYDROUS] is a strongly acidic gas. Reacts rapidly and exothermically with bases. Reacts with active metals in the presence of moisture, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas.

How long does it take to charge hydrogen iodide?

An aqueous solution containing 68.6 g of hydrogen iodide is then added to the contents of the kettle through the dropping funnel. The resulting solution is then charged for 2 minutes to a glass reaction maintained at about 85°C.

What are the dangers of hydrogen iodide anhydrous?

Hazards. HYDROGEN IODIDE, [ANHYDROUS] is a strongly acidic gas. Reacts rapidly and exothermically with bases. Reacts with active metals in the presence of moisture, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain alkenes.

What are the properties of hydrogen iodide ( HI )?

Properties of hydrogen iodide. 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 exceptionally soluble in water, giving hydroiodic acid.

How much hydrogen iodide is in one liter of water?

It is exceptionally soluble in water, giving hydroiodic acid. One liter of water will dissolve 425 liters of HI, the most concentrated solution having only four water molecules per molecule of HI. Hydroiodic acid is not pure hydrogen iodide, but a mixture containing it. Commercial “concentrated” hydroiodic acid usually contains 48–57% HI by mass.

What happens when diethyl ether is split into ethanol and iodide?

In this example diethyl ether is split into ethanol and iodoethane: The reaction is regioselective, as iodide tends to attack the less sterically hindered ether carbon. HI is subject to the same Markovnikov and anti-Markovnikov guidelines as HCl and HBr.
