SUMMARY

The oxidation number of iron (Fe) in iron(II) carbonate (FeCO3) is +2. This is determined by balancing the charges in the compound, where the carbonate ion (CO3) has a charge of -2. The discussion also mentions iron(II) nitrate, which is a different compound and may have caused confusion. Accurate identification of the compound is crucial for determining oxidation states correctly.

PREREQUISITES
  • Understanding of oxidation states in chemistry
  • Familiarity with polyatomic ions, specifically carbonate (CO3)
  • Basic knowledge of ionic compounds and their charge balancing
  • Ability to differentiate between various iron compounds, such as iron(II) and iron(III)
NEXT STEPS
  • Study the rules for determining oxidation states in compounds
  • Learn about the properties and structures of common polyatomic ions
  • Research the differences between iron(II) and iron(III) compounds
  • Explore examples of charge balancing in ionic compounds
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding oxidation states and the properties of iron compounds.

I achieved calculating the oxidation number of C and my result is x=5
Hi there,
I did an exercise and when we corrected it I realised that the oxidation number of Fe was (ll) but I don't know how can I find it.
The common name is iron (ll) nitrate and the other name, that I don't know how is called because i study this in basque, is iron (2+) nitrate trioxide (2-)

No, it is not 5.

Plus, you listed FeCO3, but then you referred to the nitrate, so it is quite difficult to help, as in reality we don't know what the problem really is.
