What is the Difference Between FeO and Fe2O3?
🆚 Go to Comparative Table 🆚The main difference between FeO and Fe2O3 lies in the oxidation state of the iron atoms and their chemical compositions. Here are the key differences:
- Oxidation State: FeO has iron in the +2 oxidation state, while Fe2O3 has iron in the +3 oxidation state.
- Chemical Composition: A molecule of ferrous oxide (FeO) contains one ferrous ion (Fe2+) and one oxygen ion (O2-), while a molecule of ferric oxide (Fe2O3) contains two ferric ions (Fe3+) and three oxygen ions (O2-).
- Appearance: FeO is a black powder, whereas Fe2O3 is a red powder.
- Uses: FeO is used in various applications, such as producing materials like plastics, heat-absorbing glass, paper, ceramics, and even rubber. It is also used to produce a type of ceramic magnet called ferrites, which are used in electronics like speakers, TVs, and computer memory cores. On the other hand, Fe2O3 is primarily used in the iron and steel industries and is an FDA-approved pigment for cosmetic use, even around the eyes.
In summary, FeO and Fe2O3 are both oxides of iron but have different oxidation states, chemical compositions, appearances, and uses. FeO has iron in the +2 oxidation state and is a black powder, while Fe2O3 has iron in the +3 oxidation state and is a red powder.
Comparative Table: FeO vs Fe2O3
The main difference between FeO and Fe2O3 lies in the oxidation state of the iron atoms in each compound. Here is a table highlighting the differences between FeO and Fe2O3:
