What type of cations are missing in the crystals of FeO with non-stoichiometric composition?

Options

  1. AFe²⁻
  2. BFe³⁺
  3. CO²⁻
  4. DO³⁻

Correct answer

B. Fe³⁺

Step-by-step solution

In crystals of FeO with non-stoichiometric composition, some Fe²⁺ cations are missing, and the loss of positive charge is compensated by the presence of Fe³⁺ ions.
