Iron(III) oxide was the most common magnetic particle used in all types of magnetic storage and recording media, including magnetic disks (for data storage) and magnetic tape (used in audio and video recording as well as data storage). Pigment Red 101 and Pigment Brown 6, are approved by the US Food and Drug Administration (FDA) for use in cosmetics. They are ferrous oxides. same cases are applied in other multi valency element like copper, cupprous and cupric. That means we have a total of -6. The most important reaction is its carbothermal reduction, which gives iron used in steel-making: Another redox reaction is the extremely exothermic thermite reaction with aluminium.[13]. Iron(III) oxide health hazards – If inhaled, iron causes irritation in the gastrointestinal tract and lungs. In concentrated aqueous alkali, Fe2O3 gives [Fe(OH)6]3−.[11]. It is also known as Hematite or Red iron oxide. [19] However, its efficacy is limited by a short diffusion length (2-4 nm) of photo-excited charge carriers[20] and subsequent fast recombination, requiring a large overpotential to drive the reaction. However, we compose Fe3O4 as FeO.

As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. It has a pH value of 7. Name the metal as it appears on the Periodic Table.

It also dissolves well in solutions of chelating agents such as EDTA and oxalic acid. Since we have two Fe atoms each one will need to be +3 to give us a +6 and balance the charges for the compound. ///// ditto, ditto Fe2O3 - exactly the same logic as above. Hematite is the characteristic component of the Swedish paint color Falu red. There are seventeen known iron oxides and oxyhydroxides, of which the best known is rust, a type of iron oxide(III). Jewelers remove the residual rouge on jewelry by use of ultrasonic cleaning. Rouge cuts more slowly than some modern polishes, such as cerium(IV) oxide, but is still used in optics fabrication and by jewelers for the superior finish it can produce.

Iron oxides are used as pigments in dental composites alongside titanium oxides.[17]. When polishing gold, the rouge slightly stains the gold, which contributes to the appearance of the finished piece.

Fe2O3 is written as iron oxide (II) while Fe3O4 is written as iron oxide (II, III). Iron (III) oxide has a density of 5.242 grams per cubic centimeter, and it is not soluble in water. It is often referred to as rust, although moisture has to be present for rust to occur. The reaction is as follows: The above image describes the structure of the Iron(III) oxide. This compound occurs naturally in rocks of all ages. Iron (III) oxide is commonly used to produce iron.
