Hint: Hematite is a common iron oxide which is mainly found in rocks and soils. It is also one of the most important ore of iron. It has the same crystal structure as ilmenite and corundum.
Complete step by step solution:
Iron oxides are chemical compounds composed of iron and oxygen. They are used as iron ores, catalyst, thermite etc. The formula of Haematite is $\text{F}{{\text{e}}_{\text{2}}}{{\text{O}}_{\text{3}}}$.
The oxidation state of iron in Hematite is + 3.
Therefore we can conclude that option C is correct.
Additional Information:
- Hematite is a reddish-black mineral consisting of ferric oxide. It is an important ore of iron.
- It is a heavy and relatively hard oxide mineral that constitutes around 70% or iron and also it is very abundant.
- There occur various forms of hematite which are called by various separate names.
- The most important deposits of hematite are sedimentary.
- It is anti ferromagnetic material below the Morin transition at 250K and weakly ferromagnetic above the Morin transition.
- It also has popularity in mourning jewelry.
- Hematite is a synthetic material sold as magnetic hematite.
- The spectral signature of hematite was also seen in the planet Mars by the infrared spectrometer.
Note: There are 16 iron oxides present. Iron oxide means which is composed of iron and oxygen. So, it is recommended to students to remember some of the common iron oxides such as magnetite, hematite and iron dioxide.
