A sample of ferrous oxide has actual formula Fe 0.93 O 1.00 . In this sample what fraction of metal ions are Fe 2+ ions? What type of non stoichiometric defect is present in this sample?
Options
- AFraction of Fe 2+ = 0.81 and Metal deficiency defect is present in this sample.
- BFraction of Fe 2+ = 0.81 and Metal excess defect is present in this sample.
- CFraction of Fe 2+ = 0.56 and Metal deficiency defect is present in this sample.
- DFraction of Fe 2+ = 0.95 and Metal deficiency defect is present in this sample.
Correct answer
A. Fraction of Fe 2+ = 0.81 and Metal deficiency defect is present in this sample.
Step-by-step solution
Correct Option is : (A) Fraction of Fe 2+ = 0.81 and Metal deficiency defect is present in this sample.
