Why do we need iron II iodine?

Ferrous iodide at room temperature for gray black solid. The chemical is FeI2 and is soluble in cold water. Iodide is used in the production of alkali metals and also used in medicine.

Iron ii iodine chemical properties

Reducibility: Oxidized by oxygen when heated in air. 4FeI2+3O2====2Fe2O3+4I2(Condition: heated)

Iron ii iodide properties and stability

Will not disintegrate if used and stored according to specifications.

Avoid contact with alkali, alkali metal, acid, moisture/moisture. It becomes grayish white in the air and deliquescent. It is easily soluble in water and has a light green color, but it turns black when the aqueous solution is heated to more than 50 ° C. The dark green tetra hydrate can be precipitated by evaporation of the aqueous solution.

Iron iodide preparation or source

1. Fe+I2====FeI2 obtained by the action of iodine and iron filings (condition: heating)

2. Fe+2HI====FeI2+H2↑ was prepared by the reaction of iron filings with hydroiodate acid

3. FeS+I2====FeI2+S prepared by heating iodine and iron sulfide (condition: heating)

4. Heating decomposition of Fe(CO)4I2 to Fe(CO)4I2====FeI2+2CO(condition: heating)

Iron ii iodide methods of storage

Dispose under dry protective gas, keep the storage unit sealed in a tight storage unit, and store in a cool, dry place.

Ferrous iodide application

Iodide can be used in the production of alkali metals. And it also can be used in medicine and used as a catalyst in organic chemistry.
