SUMMARY

The discussion focuses on identifying the appropriate valence of iron in multiple valence compounds, specifically referencing iron oxides such as FeO, Fe2O3, and Fe3O4. Each oxide represents iron in different oxidation states, which are stable under varying conditions. Understanding the context in which these compounds form is crucial for determining the correct iron valence to use in chemical reactions.

PREREQUISITES
  • Basic knowledge of oxidation states in chemistry
  • Familiarity with iron compounds and their properties
  • Understanding of chemical stability and reaction conditions
  • Knowledge of chemical nomenclature and formulas
NEXT STEPS
  • Research the properties and stability of iron oxides: FeO, Fe2O3, and Fe3O4
  • Study the principles of oxidation states and their determination in compounds
  • Explore the role of environmental conditions in chemical reactions involving iron
  • Learn about the applications of iron valence in industrial processes and materials science
USEFUL FOR

Chemistry students, educators, and professionals involved in materials science or chemical engineering who need to understand the behavior of iron in various compounds.

I found a list of all the possible valences of all elements online, but say were dealign with a compound with iron, has multiple valences, how do i know which valence to use when?

this has been bugging me for quite some time, any ideas?

There is no simple answer to that. For example, iron has (at least) three oxides, FeO, Fe2O3 and Fe3O4. Each is stable in different situations, each contains iron atoms in different oxidation states. Which, when and why - that's what the whole chemistry is about.
