Ferric iodide physical properties

Density: 2.873g/cm3

Properties: gray black solid.

Solubility: Soluble in cold water and ethanol.


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.
