Some ionic compounds contain a mixture of different charged cations. For example, wüstite is an oxide that contains both Fe 2+ and Fe 3+ cations and has a formula of Fe 0.950 O 1.00 .Calculate the fraction of iron ions present as Fe 3+ . What fraction of the sites normally occupied by Fe 2+ must be vacant in this solid?

What fraction of the sites normally occupied by Fe2+ must be vacant in this solid?
Interpretation Introduction
Interpretation:
- The fraction of Iron ions present as
- The fraction of the vacant
Concept introduction:
A compound containing mixture of ions of same element having different charges in an uneven ratio is called non-stoichiometric compound. Most of such compounds are Inorganic compounds. Transition metal elements form wide range of non-stoichiometric compounds. The variable oxidation states of the metal ions are responsible for the formation of such compounds.
Explanation of Solution
Explanation
